Wave reaction of a dipole in a circulatory double-layer flow of finite depth

An analytical solution of the problem of the wave action of a double-layer finite-depth circulatory flow on a dipole is derived. The cases in which the dipole is located in the upper and in the lower layer are considered. The values of the flow parameters at which the wave drag and the lift of the d...

Description
Summary:An analytical solution of the problem of the wave action of a double-layer finite-depth circulatory flow on a dipole is derived. The cases in which the dipole is located in the upper and in the lower layer are considered. The values of the flow parameters at which the wave drag and the lift of the dipole become maximum are determined. The examples of numerical calculations under actual sea conditions, that is, in the presence of density jumps and with account for the sea depth, are presented. The singular cases of the lift variation are established.
