Abstract

Taking KCS ship model as an example, using numerical tank technology and commercial CFD software, the free heave and trim motion of ship model sailing in infinite depth of still water is simulated in the time domain. Based on the coupled solution of ship motion equation and fluid flow equation, the VOF method is used to deal with the nonlinear free liquid surface, and the overlapping grid technique is used to deal with the grid. Finally, the relevant conditions of the ship model such as resistance, heave and trim are obtained, and the detailed information of the flow field including free surface wave, ship surface wave height and ship surface dynamic pressure are obtained at the same time, which is helpful to understand the mechanism of ship heave and trim motion. The calculated results are compared with the relevant experimental data, and the agreement with the experimental data is good.
