CFD Analysis for Rigid Moving Body at the High Tidal Environment of Sea-bed

In this paper, the basic hydrodynamic theories have been used to find the hydrodynamic factors for the underwater moving rectangular body as considered the shape of underwater walking robot. The added-mass, wave drag and lift coefficients are determined using a frequency-domain, simpl...
