Date A point or period of time associated with an event in the lifecycle of the resource 2015-06-30 Description An account of the resource The paper presents the application of artificial neural network for simulation and diagnostic purposes applied to a gas turbine powered marine propulsion plant. A simulation code for the propulsion system, developed by the authors, has been extended to take into account components degradation or malfunctioning with the addition of performance reduction coefficients. The above coefficients become input variables to the analysis method and define the system status at a given operating point. The simulator is used to generate databases needed to perform a variable selection analysis and to tune response surfaces for both direct (simulation) and inverse (diagnostic) purposes. The application of the methodology to the propulsion system of an existing frigate version demonstrate the potential of the approach.

Date A point or period of time associated with an event in the lifecycle of the resource 2015-12-30 Description An account of the resource Resistance reduction in ship becomes an important issue to be investigated. Energy consumption and its efficiency are related toward drag reduction. Drag reduction in fluid flow can be obtained by providing polymer additives, coating, surfactants, fiber and special roughness on the surface hull. Fish skin surface coated with biopolymers viscous fluid (slime) is one method in frictional resistance reduction. The aim of this is to understanding the effect of drag reduction using eel slime biopolymer in unsymmetrical trimaran ship model. The Investigation was conducted using towing tank test with variation of velocity. The dimension of trimaran model are L = 2 m, B = 0.20 m and T = 0.065 m. The ship model resistance was precisely measured by a load cell transducer. The comparison of resistance on trimaran ship model coated and uncoated by eel slime are shown on the graph as a function of the total drag coefficient and Froude number. It is discovered the trimaran ship model by eel slime has higher drag reduction compared to trimaran with no eel slime at similar displacement. The result shows the drag reduction about 11 % at Fr 0.35.

Since such problems are not conducive to physical modeling and experimental validation due to their size and speeds involved, numerical analysis is an accepted norm. However conventional means to study structural responses using a three dimensional runway with time varying dynamic loads is numerically difficult and time consuming. The analysis is made simpler by assuming the airport to be a simple, infinitely long beam, given by a one dimensional Timoshenko-Mindlin plate equation, in contact with the water surface. In developing this expression, a Fourier transformation in space in wave number domain is utilized rather than using the wave propagation method to reduce the analysis to a substructure. On analyzing, the structural response is seen as local peaks emanating from the point of load application which moves in a curvilinear path with increasing speed of the airplane. The location of these peaks a priori is however not feasible.DOI: http://dx.doi.org/10.3329/jname.v11i2.19167 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/19167 10.3329/jname.v11i2.19167 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/19167/14640 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 11 No. 2 (2014); 131-138 2070-8998 1813-8535 Subject The topic of the resource Moving load Timoshenko-Mindlin beam Floating runway Structural response Title A name given to the resource Structural response of a floating runway excited by the taking off of an airplane 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.

In this paper, the water entry of several arbitrary bow sections is investigated. For this purpose, arbitrary bow shapes which are introduced by Lewis form approximation are considered. In order to obtain pressure distribution and free surface profile, volume of fluid (VOF) method coupled with finite volume method (FVM) are utilized in Ansys-CFX solver. The main feature of present study is consideration of some new arbitrary bow sections which have not been previously studied. Another motivation of the current work is investigation of water entry of arbitrary bow sections using a coupled numerical solution of FVM/VOF. Pressure distribution, free surface, and evolution of intersection point on bow sections are presented, while secondary water impact is demonstrated. Comparison of selected current findings against the results of previous studies indicates favorable agreement.DOI: http://dx.doi.org/10.3329/jname.v11i2.18724 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/18724 10.3329/jname.v11i2.18724 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/18724/14611 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 11 No. 2 (2014); 117-129 2070-8998 1813-8535 Subject The topic of the resource Water entry Arbitrary bow sections Pressure distribution Finite volume method Volume of fluid Title A name given to the resource Numerical simulation of water entry of different arbitrary bow sections Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Numerical Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Should the energy possessed by these waves be harnessed, it can be one of the popular green energy systems. Present study aims at the design and development of a new device that can be fitted on an offshore semisubmersible platform and can produce electricity to meet their operational energy demands partially. Few wave energy devices are developed in the recent past; Common idea in all such devices is that they harness heave, or surge energy of the wave. In the present study, heave energy of the buoy is converted to mechanical work by deploying hydraulic cylinders and a motor. The generated power from the waves shall be primarily utilized in the semi-submersible platform for deep sea mining application.DOI: http://dx.doi.org/10.3329/jname.v11i2.18420 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/18420 10.3329/jname.v11i2.18420 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/18420/14642 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 11 No. 2 (2014); 139-146 2070-8998 1813-8535 Subject The topic of the resource Ocean wave energy wave energy float wave power wave energy experiment deep ocean energy lever mechanism.

The flow is permeated by a uniform transverse magnetic field. A scaling group of transformations is applied to the governing equations. The system remains invariant due to some relations among the parameters of the transformations. After finding three absolute invariants, a third-order ordinary differential equation corresponding to the momentum equation, and two second-order ordinary differential equations corresponding to energy and diffusion equations are derived. The coupled ordinary differential equations along with the boundary conditions are solved numerically. The effects of various parameters on velocity, temperature and concentration fields as well as skin-friction, Nusselt number and Sherwood number are presented graphically and in tabulated form.

Inadequate representation of the components of a typical random sea might lead to poor performance of the control system. A multiple output system such as the one having components of wave elevation and slope, facilitates designing the control system taking into account the different degrees of freedom. The method of modelling the sea environment presented here, provides the basis for the design of motion control systems for multiple degree of freedom cases, which give rise to excitation forces and moments acting on the marine vehicle. The method used here models the sea environment using Gaussian white noise and shaping filter to generate a multiple output form of the random sea state.  In the first step a given standard wave spectrum is approximated using a rational polynomial, the coefficients of the polynomial are obtained by least square fitting method to best match the spectrum. The established rational polynomial is then decomposed to get the transfer function of the shaping filter. The wave slope spectrum is similarly approximated using the same rational polynomial. The transfer functions of the two components of amplitude and slope,  representing the filters are combined to generate a state space form. Using the white noise as input, the state space form obtains the wave elevation and slope as outputs. By performing spectral analysis using Welch method, the quality of the obtained output is checked against the targetted spectrum. The application of the simulated wave slope spectrum in a closed loop state space model is demonstrated as applied to  the roll stabilization characteristics of a stationary ship using a passive tank.DOI: http://dx.doi.org/10.3329/jname.v11i1.17768 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/17768 10.3329/jname.v11i1.17768 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/17768/13336 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 11 No. 1 (2014); 29-38 2070-8998 1813-8535 Subject The topic of the resource Shaping filter White noise Rational polynomial Least square fitting State space model Title A name given to the resource Sea wave modelling for motion control applications 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.

A magnetic field of uniform strength is assumed to be applied normal to the plate. The equations governing the fluid flow which are highly nonlinear are reduced to linear by using perturbation method and have been solved subject to the relevant boundary conditions. It is noted that the velocity of the fluid is increased as Soret number and suction parameter increase, whereas reverse phenomenon is observed in case of magnetic field strength and sink strength.

Panneer Srinivasan, Nagan Date A point or period of time associated with an event in the lifecycle of the resource 2014-12-18 Description An account of the resource Tension Leg Platforms (TLPs) are one of the reliable structures for offshore industry in deep waters because of its motion characteristics in heave, roll and pitch degrees of freedom. Heave motion is very important in offshore facilities and have to kept as minimum as possible. As the water depth increases TLPs suffers from some limitations and hence has to be modified to cater to deeper waters. One such concept proposed is Tension Based Tension Leg Platform (TBTLP). In this paper, experimental investigations carried out on a scaled model of a Tension Based Tension Leg Platform in regular waves are reported. This is the first ever experiments that was carried out on a scaled model of the new concept. To investigate the effect of Tension Base, experiments were also conducted on the TLP (without Tension Base) in two different water depths. RAOs have been compared for surge and heave dof of TLP and TBTLP. Numerical modeling of the TLP and TBTLP responses using ANSYS AQWA software are included as well for comparisons.DOI: http://dx.doi.org/10.3329/jname.v11i2.17341 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/17341 10.3329/jname.v11i2.17341 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/17341/14570 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 11 No. 2 (2014); 105-116 2070-8998 1813-8535 Subject The topic of the resource Tension leg platorm Tension Base Response amplitude operator (RAO) Modeling Model Tests Regular wave Title A name given to the resource Experimental investigations on tension based tension leg platform (TBTLP) Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion
