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,…
A numerical analysis has been conducted to show the effects of magnetohydrodynamic (MHD) and Joule heating on heat transfer phenomenon in a lid driven triangular cavity. The heat transfer fluid (HTF) has been considered as water based hybrid…
This contribution presents a computational simulation for a generic hull shape with attached short pin-protuberance for its hydrodynamic characteristics. This work is a part of a large framework of numerical simulation and experimentation carried out…
Ship recycling in Bangladesh has been playing as a catalyst for the economy by supporting steel industry, shipbuilding industry and other industries and it has also been generating huge employments for the country. But, existing problems of this…
In this paper, an effort has been made to evaluate the present shipbuilding industries in Bangladesh. To do this, at first an overall picture of this industries have been depicted by identifying the actual shipbuilding practice in both public and…
Hull form optimization from a hydrodynamic performance point of view is an important aspect of ship design. This paper presents a computational method to estimate the ship resistance (viscous & wave) in calm-water. In the optimization process the…
The aim of the present study is to develop closed-form formulations for predicting the ultimate compressive and tensional strength of stiffened steel panels with crack damages. First, a numerical database is generated. This database includes the…
