Effects of the Influence of a Wave on an Underwater Obstacle by a Stratified Flow of Finite Depth

Equations are obtained for a hydrodynamic load on an obstacle, which is modeled by a point dipole during its circulated flow of a two-layered liquid of finite depth. The correlations between the wave resistance and rising force and the rate of the flow and circulation are studied. Examples of numeri...

Description
Summary:Equations are obtained for a hydrodynamic load on an obstacle, which is modeled by a point dipole during its circulated flow of a two-layered liquid of finite depth. The correlations between the wave resistance and rising force and the rate of the flow and circulation are studied. Examples of numerical calculations for real marine conditions are given. It is shown that the account of circulation can significantly change the value of the hydrodynamic reaction, which impacts the dipole.
