A computational fluid dynamics study on the design optimization of an autonomous underwater vehicle

Abstract

In this study, numerical computation is used to develop a physical model representing all important features of the Autonomous Underwater Vehicle's (AUV) shape using the finite element methods. Because the shape of the AUV is an essential factor in determining the application and the vehicle's capability, investigating the effect of the environment on this profile is needed. This paper illustrates using Computational Fluid Dynamics (CFD) to investigate the effect of fluid flow on the AUV's profile at different velocities. The results obtained from the numerical computation demonstrate some of the hydrodynamic values of the AUV's shape, such as drag force and stress. It is necessary for optimizing the design of an AUV. When the AUV moves, the maximum pressure occurs at the nose of an AUV.
