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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
