Abstract

Simultaneous vertical movement of the elliptic cylinder and a horizontal wall (bottom) is considered which have been completely submerged in ideal incompressible liquid on small times. The feature of this task is that under certain conditions a liquid separation from a body occurs as a result of which near a body the cavity is formed and a new internal free border emerges. Generalization of the received results is given in case of detachable acceleration of the circular cylinder which has been partly submerged in liquid.

Keywords:

ideal incompressible liquid, elliptic cylinder, free border, cavity, small times, Frud number, cavity number
