Nowadays, remotely operated vehicle (ROV) is an integral part of the marine industry. In this study, the hydrodynamic performance of a specific model of ROV is evaluated by numerical and experimental simulations in
different Reynolds numbers ranging from 39291 to 157163 and various angles of attack from 0? to 45?. Moreover, two rectangular cubic models with fillet and sharp edges are modeled for comparative study. The wind
tunnel and the finite volume methods are used for experimental and numerical simulations, respectively, and the
Menter’s SST k-? model is employed to simulate the turbulent flow. The leading edge geometry, angle of attack,
and Reynolds number are found to be the most effective factors on the drag forces. Additionally, the fillet edge
model had better hydrodynamic performance than the ROV and the sharp edge rectangular cubic model
considerably.
