Abstract
Analytical expressions are obtained describing the hydrodynamic response to the circulation of flow of a two-layer fluid of finite depth around a point dipole. The dependences of the wave resistance and lifting force on the flow velocity, density jump, circulation, and depth of the sea are investigated. It is shown that the influence of the velocity circulation leads to a change in the lifting force applied to the dipole. Such changes are reversible in a relatively narrow range of the flow velocity around a pipeline. In addition to the flow around a pipeline, similar properties of the effect of circulation on the lifting force can also appear around self-propelled underwater objects and aircrafts.
