Hydrodynamic Characteristic Studies of Underwater ROV. ANSYS – Fluent Simulation

This paper presents the hydrodynamic characteristic of remotely operated underwater vehicle (AUV). Using a AUV model achieved in laboratory of Constanta Maritime University, we study the hydrodynamics of the submarine using simulation to observe the floatability and the motors position. We consider the four forces on the ROV: their own weight, the Archimedes' force, the propulsion of motors and the traction force. Using some simulation, we link the traction force with the speed considering the main direction. According to the fundamental principle of statics, to maintain a constant speed, such as speed maximum, all forces must mutually cancel each other. So by designing according to each vector of the landmark. This paper is focused on how ANSYS-Fluent can point out design problems at the virtual prototype.
