The investigations are carried out for varying wave characteristics and depth of water 0.50 m. In an experimental study, to understand the model and scale effects for the desired wave conditions is a critical task in all-time conditions. So, it is also necessary to develop an appropriate numerical model to understand the hydrodynamics of the selected test model. Using the Volume of Fluid (VOF) method and incompressible open channel fluid flow a 2D numerical wave flume is developed using ANSYS- Fluent platform. The wave boundary conditions are adopted by solving the Reynolds-Averaged Navier Stokes equations (RANS equation) and especially with k—ε model to examine the effects of turbulence on the numerical results. The wave forces, wave runup, and wave reflection characteristics on the test model are measured for different wave characteristics, and results obtained from the numerical investigations are comparable with the experimental results to evident the relevance of the developed numerical model.

The system is rotated around the vertical axis in the clockwise direction over the Taylor number (Tr) ranging from 0 to 2000 keeping the other parameters constant as aspect ratio Ar =3, curvature ratio BETA=0.5 the Dean number Dn = 1000 and the Prandtl number Pr = 7.0 (water). To reveal steady solution (SS) curves, we applied path continuation technique and obtained five asymmetric SS curves comprising with 2- to 8-pair cell. A bar diagram is also drawn to visualize, at a glance, longitudinal vortex generation on various curves of steady solutions. To explore unsteady behavior, time-progression analysis is performed and flow characteristics are precisely determined by obtaining phase space trajectory of the solutions. The transient flow demonstrates various stages of physically realizable solutions including chaotic, multi-periodic, periodic and steady-state; and it is found that the number of secondary vortices declines as Tr is increased. Convective heat transfer (CHT) is computed and the corresponding dependence on the flow stages is discussed accurately. Finally, a comparison has been made between the numerical computation and experimental investigations which shows a benchmark agreement.   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/51972 10.3329/jname.v18i2.51972 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/51972/39884 Rights Information about rights held in and over the resource Copyright (c) 2021 Journal of Naval Architecture and Marine Engineering http://creativecommons.org/licenses/by-nc/4.0 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 18 No. 2 (2021); 187-205 2070-8998 1813-8535 Title A name given to the resource A computational study on flow characteristics and energy distribution in a rotating coiled rectangular duct with longitudinal vortex generation 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 2021-06-28 Description An account of the resource The main objective of this paper is to focus on a numerical study of unsteady boundary layer flow of Williamson Nanofluids over a heated permeable stretching sheet embedded in porous medium in the presence of viscous dissipation. A mathematical modeled which resembles the physical flow problem has been developed. By using an appropriate transformation, we converted the system of dimensional nonlinear partial differential equations into system of coupled dimensionless ordinary differential equations. Numerical solutions of these equations are obtained by Runge-Kutta fourth order with shooting method.  The velocity, temperature and concentration distributions are discussed numerically and presented through graphs. The numerical values of reduced skin-friction coefficient, Nusselt number and Sherwood number at the plate are derived and discussed numerically for various values of physical parameters which are presented through tables. The present results have been compared with existing one for some limiting case and found excellent validation. It is analyzed that the reduced skin friction coefficient enhances with increasing values of an unsteady parameter, magnetic parameter and porosity parameter. In addition, we observe that decrement in velocity profile of the fluid flow is observed for increasing values of the non-Newtonian Williamson parameter and a rise in Eckert number leads to the enhancement of the temperature of the fluid in the thermal boundary layer.

Date A point or period of time associated with an event in the lifecycle of the resource 2021-12-31 Description An account of the resource In shipbuilding, the process of forming flat metal plate into curved hull plates with compound shapes is very important and has greatly affected many economic and technical factors such as strength, quality, and aesthetics of the hull, construction cost and time, etc. Currently, the forming method of curved hull plates by line heating is used effectively and commonly in many shipyards, however, its main problem is very difficult to determine where and how much to heat on the flat metal plate to obtain the plate of a certain shape. In this article, a finite element model is established and adjusted based on the actual data to numerical simulate the process of forming hull plates by using flame torch line heating. Base on this, the suitable position and temperature for the heating lines in the forming process are determined to form a metal plate into hull plates with the exact desired shapes. This research has been applied for forming by torch line heating of two plates, denoted K1 and K10, in the bulb bow of a 20,000 DWT cargo ship, built at Camranh Shipyard in Vietnam with the deformation deviations between the actual and desired plate surfaces are within ± 3%.    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/51412 10.3329/jname.v18i2.51412 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/51412/39863 Rights Information about rights held in and over the resource Copyright (c) 2021 Journal of Naval Architecture and Marine Engineering http://creativecommons.org/licenses/by-nc/4.0 Source A related resource from which the described resource is derived Journal of Naval Architecture and Marine Engineering; Vol. 18 No. 2 (2021); 109-125 2070-8998 1813-8535 Title A name given to the resource A new approach to determining heating parameters suitable for hull plate forming by torch line heating 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.

At the same time, the energy extraction from the abundant marine renewable energy resources available offshore need more development due to difference in the levelized cost of energy (LCOE) compared to energy extracted onshore, though the difference in the cost of energy is getting reduced faster than expected. Meanwhile hundreds of offshore platforms already existing in oil and gas industry will undergo decommissioning at the end of its life; which will require the platform to be removed or reused. In this context, the reuse possibility of such decommissioned offshore platforms to be used as support structures for marine renewable energy applications is examined. This paper presents a review on the research efforts on this topic and a discussion on the various aspects involved in the possible reuse of decommissioned offshore fixed platforms for marine renewable energy applications.

Date A point or period of time associated with an event in the lifecycle of the resource 2021-06-11 Description An account of the resource The utilization of the existing breakwater constructions into wave energy conversion has been often adopted to rendering a revenue of the capital cost of investment. The paper has contributed to viable concept of a new integration design through more effectively capturing wave-overtopping which finally converts into electrical energy. This design is hereafter called Overtopping Breakwater for Energy Conversion (OBREC). The development of an experimental test of the current OBREC has been conducted to obtain a proper ramp shape through evaluating the amounts of the wave-overtopping discharges into the reservoir incorporated with wave-reflection coefficients. To achieve the objective, several geometry ramps such as linear, convex, concave and cubic shapes have been experimentally investigated at the National Research Institute Malaysia (NAHRIM) laboratory. The experimental study showed that the cubic-ramp shape has resulted in more significant amount of the wave-overtopping discharge into the reservoir associated with the low wave-reflection coefficient than the other ramp shapes. In general, it is merely concluded that this investigation provides very promising concept of the new proposed OBREC design to harness the larger wave energy.

Date A point or period of time associated with an event in the lifecycle of the resource 2020-12-30 Description An account of the resource During voyage of a ship from one port to another, different types of wastes generated due to operation of the ship and livelihood of the crews, which fall under the scope of international convention for the prevention of pollution from ships, MARPOL 73/78. It is seen that almost 1000 nos. of ships are calling in to Mongla port every year which is gradually increasing day by day. However, there is no waste management system in the port now. IMO has recognized that provisions of proper wastes collection vessel as well as oil spill management vessel and reception facilities are crucial for effective MARPOL implementation in the maritime port. In view of the same, the feasibility of establishment of a standard and modern waste management system for Mongla port has been studied. First of all, amount of different types of wastes sourced from the shipping operation at the port of Mongla has been estimated following standard procedure and to facilitate the necessary services to incoming ships, a proposal has been made to procure a waste collection vessel, oil spill collection vessels and port reception and treatment facilities by Mongla Port Authority along with other necessary vessels and equipment. The procurement, operation and maintenance costs as well as revenue to be collected from the incoming ships for wastes quantities, alternative uses of the vessels and facilities and earnings from selling the product of the treatment have been examined. It is found from the study that the investment is technically, financially and economically viable.
