Submarines play an important role in the military defense industry of the countries.
In this study, it is aimed to investigate the flow distribution ,the pressure and resistance parameters affecting the surface of the submarines, which will be investigated in three dimensions in terms of engineering, simulated by computer programs. In order to correctly examine the hydrodynamic pressure formed around the submarine, the transverse flow on the boundary layer will be examined. In these studies, the three-dimensional flow area of the submarines will be examined using the Computational Fluid Dynamics (CFD) and the Finite Volume Method (FVM) with the aid of the ANSYS-Fluent ™ software program. The turbulent flow field will be simulated using the Finite Volume Stress analysis method and the k-? turbulence model in the turbulent flows that will be measured along the surface so that the calculations can give more realistic results. In this article, two different types of submarines will be selected to work on and the nearest forms will be created to the real of these submarines. Primarily, with RhinoCeros ™ software, simple two-dimensional forms will be drawn based on sphere, cone and cylinder shapes.
It is planned to create a basic idea about the project by calculating the flow area around these drawn forms. By developing the models on RhinoCeros ™ it was aimed to create the general form of the submarines mentioned for the purpose of the project. Designing the models of submarine varieties that are referred to while creating the targeted submarine forms is the most important criterion to design the closest to reality. The velocity values of the submarine forms to be analyzed with the help of the ANSYS Fluent ™ program will be measured at different speeds, starting from 5 knots and increasing by 5 knots to 20 knots. Nowadays, computer software, which has an important place in the practical and correct solution of engineering problems, will be basis for this study.
