Abstract

All moving vehicles on the earth resist by the fluids which they are transmitting through. Fluids are of two types, liquids and gases. Resistance offered by the fluids depends on fluid properties, gases offer lower resistance than the liquids. All transporting and marine vehicles are subjected to various kind of resistance in which former is applicable to air resistance and latter is by fluid resistance. Moving bodies which are in direct contact with land , there is no point in considering course stability as it is zero or negligible, but for the moving bodies which floats on the fluid it is imperative to consider the course stability and calculated accordingly as proceeded or shown below, For ex: aerospace vehicles and moving marine vehicles. Course stability is the term which also means directional stability. The directional stability mainly depends on the geometry of moving body, environmental conditions also cause course deviation. Now a days marine vehicles are playing vital role to transport goods from one place to another. In the present study course study of ocean going barge is considered. Skeg is the sternward extensions to marine vehicles which is intended to keep the moving vehicle in straight path. Computations fluid dynamics (CFD) is the study of fluid flow around the objects which are subjected to fluid impact.
