Modeling of Wave Regimes and Control Parameters at Body Motion under the Water

摘要

The problem of surface gravity waves generation under the motion of the ellipsoid submerged in a liquid half-space is considered. The problem for a sphere was considered as a special case. Using the mirror transformations for deviation of a free surface there were obtained the exact analytical solutions. The analysis found the existence of motion characteristic regimes under which the form of a free surface can essentially differ. On the basis of numerical simulation there was also investigated the problem for the elliptical wing with the conic nose part deflected with respect to a current. It was shown that the wave drag increased with a noise deflection.
