Resistance performance simulation of remotely operated vehicle in deep sea considering propeller rotation

In order to predict the resistance performance and movement stability of deep-sea remotely operated vehicle quickly and accurately, the steady-state Reynolds-averaged Navier–Stokes method is used to simulate the force of open-frame remotely operated vehicle with propeller in motion. Volume force model is adopted to simulate the interaction between the propeller and the remotely operated vehicle, solving the force of remotely operated vehicle under the continuous work of two or four screw propellers in the horizontal and vertical motion, as well as the propeller thrust and shaft torque. In addition, according to the simulation result, the shaft torque of the symmetrical distributed propeller is almost equal, so it will not affect the movement stability of remotely operated vehicle. Since no experimental results of these drags and torques have not been performed in this study, it is important to validate the computational fluid dynamics methodology with experimental data and associated motion phenomena by means of numerical simulation. This is the preliminary design stage where extensive hydrodynamic test facilities are not available.
