Optimization and Analysis of the Hydrodynamic Coefficients for an Underwater Vehicle (UV) Laboratoire

The present paper achieves a numerical study to improve the performance of an optimal hull of an underwater vehicle using iso-geometrics equations of the model SUBMARIN hull and ANSYS CFX software package for Computational Fluid Dynamics. The study is twofold. First, evaluate and calibrate the CFD model for the underwater vehicle, second, the previous concept are transferred in order to obtain numerical results for AUV optimization and analysis. Optimization results for compliance criterions which allow controlling the shape such as drag coefficient is presented. The numerical results show a good agreement with those of the experimental one. Thus, an analysis of the coefficients of the added masses coefficients and the damping force are carried to help to understand the AUV acceleration behavior at sea.
