Abdul Date A point or period of time associated with an event in the lifecycle of the resource 2010-06-23 Description An account of the resource In this present work the effects of temperature dependent viscosity and thermal conductivity on the coupling of conduction and Joule heating with MHD free convection flow along a semi-infinite vertical flat plate have been analyzed. The governing boundary layer equations with associated boundary conditions for this phenomenon are transformed to non-dimensional form using the appropriate variables. By the help of the implicit finite difference method with Keller–box scheme, the resulting non-linear system of partial differential equation is then solved numerically. The purpose of this paper is to study the skin friction coefficient, the surface temperature, the velocity and the temperature profiles over the whole boundary layer for different values of the Prandtl number Pr, the magnetic parameter M, the thermal conductivity variation parameter, the viscosity variation parameter and the Joule heating parameter J. The results indicate that the flow pattern, temperature field and rate of heat transfer are significantly dependent on the above mentioned parameters. The local skin friction co-efficient and the surface temperature profiles for different values of viscosity variation parameter are compared with previously published works and are found to be in good agreement.Keywords: Viscosity; thermal conductivity; Joule heating; MHD; conduction; free convection.DOI: 10.3329/jname.v6i2.4994 Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context https://www.banglajol.info/index.php/JNAME/article/view/4994 10.3329/jname.v6i2.4994 Language A language of the resource eng Publisher An entity responsible for making the resource available Association of Naval Architects and Marine Engineers Relation A related resource https://www.banglajol.info/index.php/JNAME/article/view/4994/4223 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 6 No. 2 (2009); 72-83 2070-8998 1813-8535 Subject The topic of the resource Viscosity thermal conductivity Joule heating MHD conduction free convection Title A name given to the resource MHD free convection flow along a vertical flat plate with thermal conductivity and viscosity depending on temperature Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Keller-box method Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

The boundary layer equations have been transformed into dimensionless coupled nonlinear ordinary differential equations by appropriate transformations. The similarity solutions of the transformed dimensionless equations for the flow field and heat and mass transfer characteristics are obtained by shooting iteration technique. Numerical results are presented in the form of primary and secondary velocities, temperature and concentration distributions within the boundary layer for different parameters entering into the analysis. Finally, the effects of the pertinent parameters on the Skin-friction coefficients, Nusselt number and Sherwood number are also examined.Keywords: MHD; Joule heating; porous medium; rotating system simulation. doi: http://dx.doi.org/10.3329/jname.v8i2.5055 Journal of Naval Architecture and Marine Engineering 8(2011) 105-120 Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context https://www.banglajol.info/index.php/JNAME/article/view/5055 10.3329/jname.v8i2.5055 Language A language of the resource eng Publisher An entity responsible for making the resource available Association of Naval Architects and Marine Engineers Relation A related resource https://www.banglajol.info/index.php/JNAME/article/view/5055/6950 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 8 No. 2 (2011); 105-120 2070-8998 1813-8535 Subject The topic of the resource MHD Joule heating porous medium rotating system simulation Title A name given to the resource Viscous dissipation and Joule heating effects on steady MHD combined heat and mass transfer flow through a porous medium in a rotating system Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Date A point or period of time associated with an event in the lifecycle of the resource 2011-03-16 Description An account of the resource This paper presents a numerical study of the non-cavitating and cavitating flow around CAV 2003 hydrofoil. The phenomenon of cavitation is modeled through a mixture model. For the numerical solution of cavitating flow a bubble dynamics cavitation model is used to describe the generation and evaporation of vapor phase. The non-cavitating study focuses on the influence of the turbulence model and different mesh sizes used in the computation. Three turbulence models such as Spalart-Allmaras, Shear Stress Turbulence (SST) k-? model, RNG k-? with enhanced wall treatment are used to capture turbulent boundary layer along the hydrofoil surface. The results predicted by these models are compared with each other. The cavitating study first presented an unsteady behavior of the partial cavity attached to the foil. Then, an analysis of a supercavitating condition is performed. The predicted results show good agreement with results published by other researchers.DOI: 10.3329/jname.v7i2.5270 Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context https://www.banglajol.info/index.php/JNAME/article/view/5270 10.3329/jname.v7i2.5270 Language A language of the resource eng Publisher An entity responsible for making the resource available Association of Naval Architects and Marine Engineers Relation A related resource https://www.banglajol.info/index.php/JNAME/article/view/5270/5605 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 7 No. 2 (2010); 51-60 2070-8998 1813-8535 Title A name given to the resource Numerical study of unsteady flow around a cavitating hydrofoil Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

The specimens are kept in chloride solution (20% NaCl) up to 240 hours. At every 48 hours, thickness and weight loss is measured and tension test is carried out. It was found that the susceptibility of the steels to corrosion based on their weight loss were identical prior to 144 hours, after that is accelerated for high strength steel. In addition, it was found that manganese (Mn) has reduced corrosion rate at early stage of corrosion. The change in mechanical properties by corrosion for all steels are the same, and ultimate strength is reduced, which for limit state design of aged structure should be taken into account.DOI: 10.3329/jname.v7i2.5309 Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context https://www.banglajol.info/index.php/JNAME/article/view/5309 10.3329/jname.v7i2.5309 Language A language of the resource eng Publisher An entity responsible for making the resource available Association of Naval Architects and Marine Engineers Relation A related resource https://www.banglajol.info/index.php/JNAME/article/view/5309/5655 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 7 No. 2 (2010); 94-100 2070-8998 1813-8535 Subject The topic of the resource Chloride solution Corrosion rate carbon steel Tension test Title A name given to the resource Mechanical properties and corrosion resistance of normal strength and high strength steels in chloride solution Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Experimental Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

To do this, at first an overall picture of this industries have been depicted by identifying the actual shipbuilding practice in both public and private sector. Relevant data have been explored through extensive review of literature, field visits, interacting with shipyard and Ship owners, shipyard managers, Government regulatory and monitoring bodies using structured, unstructured and open ended questionnaires. Existing and upcoming yards have been identified and yards have been categorized by describing the shipyard in terms of modern shipbuilding requirements. The labor cost, labor hour, relative labor rate, productivity etc. have been quantified and compared with other nations. An investigation of cost breakdown of a sample exportable quality ship has been assessed to find out percentage of local components of total cost structure. The potentiality, capability and problems of the shipbuilding sector of Bangladesh have been identified & some recommendations have been made in line with this study.DOI: 10.3329/jname.v7i2.5407 Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context https://www.banglajol.info/index.php/JNAME/article/view/5407 10.3329/jname.v7i2.5407 Language A language of the resource eng Publisher An entity responsible for making the resource available Association of Naval Architects and Marine Engineers Relation A related resource https://www.banglajol.info/index.php/JNAME/article/view/5407/5654 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 7 No. 2 (2010); 73-82 2070-8998 1813-8535 Subject The topic of the resource Shipbuilding Data collection Potentiality Title A name given to the resource Evaluation of the performance of contemporary shipbuilding industries in Bangladesh Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Shahidul Date A point or period of time associated with an event in the lifecycle of the resource 2011-12-30 Description An account of the resource Automatic hexahedral mesh generation is a very deserving solution for better performance of finite element analysis of complex large structures. At present plastering, whisker weaving and whisker weaving based plastering algorithm are available to perform such tasks. As these hexahedral mesh generation processes are fully automatic, it is possible to form some elements, which don’t have high enough qualities for finite element analysis. For this reason, a reliable post-processing method is presented in this paper which can modify the shapes of the already generated hexahedrons. Four different structural models are tested and the results show that the proposed method can effectively modify the quality of the inverted hexahedrons and eliminate the invalid ones.Keywords: Doublet; triplet; quadruplet; Whisker weaving based plastering algorithm; hexahedral meshDOI: http://dx.doi.org/10.3329/jname.v8i2.5646Journal of Naval Architecture and Marine Engineering 8(2011) 121-128 Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context https://www.banglajol.info/index.php/JNAME/article/view/5646 10.3329/jname.v8i2.5646 Language A language of the resource eng Publisher An entity responsible for making the resource available Association of Naval Architects and Marine Engineers Relation A related resource https://www.banglajol.info/index.php/JNAME/article/view/5646/6940 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 8 No. 2 (2011); 121-128 2070-8998 1813-8535 Subject The topic of the resource Doublet triplet quadruplet Whisker weaving based plastering algorithm hexahedral mesh Title A name given to the resource Improving the quality of hexahedral mesh generated by automatic mesh generators Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

The similarity solutions of the transformed dimensionless governing equations are obtained by series solution. It is found that, velocity is reduced considerably with a rise in conduction-radiation parameter (R) or Hartmann number (M) whereas the skin friction is found to be markedly boosted with an increase in M or Magnetic Prandtl number (Pm). An increase in magnetic body parameter (M) or Magnetic Prandtl number (Pm) is found to escalate induced magnetic field whereas an increase in R is shown to exert the opposite effect. Applications of the study include laminar magneto-aerodynamics, materials processing and MHD propulsion thermo-fluid dynamics.DOI: 10.3329/jname.v7i2.5662 Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context https://www.banglajol.info/index.php/JNAME/article/view/5662 10.3329/jname.v7i2.5662 Language A language of the resource eng Publisher An entity responsible for making the resource available Association of Naval Architects and Marine Engineers Relation A related resource https://www.banglajol.info/index.php/JNAME/article/view/5662/5629 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 7 No. 2 (2010); 61-72 2070-8998 1813-8535 Subject The topic of the resource Electrically-conducting Chemical reaction Radiating fluid Series solution technique Current Density and Magnetic Prandtl number.

The channel is subjected to the transverse magnetic field. The coupled governing equations are solved subjected to the boundary conditions proposed by the previous authors using F.E.M. The results are compared with Kumar et al (2010). It is found that the increase in the magnetic field reduces the micro rotation (N) and velocity and enhances the temperature. Increase in the Eckert (Ec) number, decreases the velocity, temperature and micro rotation. The Nusselt number and shear stress values are also analyzed.DOI: http://dx.doi.org/10.3329/jname.v8i1.5808 Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context https://www.banglajol.info/index.php/JNAME/article/view/5808 10.3329/jname.v8i1.5808 Language A language of the resource eng Publisher An entity responsible for making the resource available Association of Naval Architects and Marine Engineers Relation A related resource https://www.banglajol.info/index.php/JNAME/article/view/5808/5871 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 8 No. 1 (2011); 59-69 2070-8998 1813-8535 Subject The topic of the resource Micropolar fluid viscous fluid Vertical Channel Viscous dissipation MHD FEM Title A name given to the resource Finite element analysis of free convection flow with MHD micropolar and viscous fluids in a vertical channel with dissipative effects Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Quasi-Experimental
