AbstractRemotely Operative Vehicles ROV s are used in many applications such asoceanography mining fishing and etc Dynamic simulation and control of these vehiclesto maneuver in limited areas is impossible without finding hydrodynamic forces It s anessential task to calculate these forces to increase their performance and suitablecontrolling In present work at the first step geometry of Kavosh 4 underwater vehicle is modeled witha suitable mesh generator Then the governing 3D incompressible Navier Stokes equationsare solved by means of a finite volume based commercial code in steady and unsteadycases In this simulation ROV hydrodynamic coefficients are estimated in defined motions These motions include horizontal and vertical movement with and without acceleration andmoving with angel of attack Also center of pressure which is important in vehicle stabilityis calculated in forward moving for different velocities Considering hydrodynamic forcesin accelerating motion include two parts actual and virtual force Morrison s equation isused to separating these two parts Results are validated with simulating the same casewhich has experimental data
