Abstract: 

The aim of the present study is to investigate the superiority of steady tests simulations relative to the unsteady experiments, especially planar motion mechanism tests (PMM), for computing velocity-based hydrodynamics coefficients. Using CFD analysis, steady maneuvers including towing with drift and attack angles together with rotating arm tests are simulated in order to calculate the linear damping coefficients of a prototype submarine. Comparisons of the obtained results with available unsteady experimental results of the SUBOFF submarine show the reliability of the methods used in this paper. It also demonstrates the accuracy and simplicity of the present simulations due to the steady nature of simulations. In order to compute the linear damping coefficients, the simulations have been performed in small values of the attack and drift angles and angular velocities for the towing and rotating arm tests, respectively.
