| Abstract: | We studied the surface perturbations of a two-layer ideal fluid induced by a flow past a submerged obstacle (simulated by
a point dipole) in the vicinity of the density-jump layer. It is shown that the formation of two different types of surface
waves is possible behind the flowed past obstacle in the real conditions of the open sea. The comparison of the amplitudes
of the surface perturbations induced by the obstacle located above and below the density jump revealed their significant differences,
which seems to be important for the use of this effect in practical problems. |
