Summary:Hydrodynamic effects are critical in the performance of an underwater vehicle. This paper mainly focuses on the hydrodynamic modelling of the Autonomous Underwater Vehicle (AUV) and the simulation study of the AUV with different tail angles and length using ANSYS Fluent. The tail angle of -45° to 45° and a tail length of 0 to 40% of the length of the hull are considered for simulation works. Computational studies are carried out with a constant velocity of 1 m/s with a realizable K-ε model. Finally, the results are compared with the increase in buoyancy of the vehicle to deduce an optimum tail length and angle for the AUV.
