Abstract
The paper presents a numerical method for calculating the hydrostatic and hydrodynamic reactions of marine underwater objects moving in an arbitrary manner under conditions of internal waves and sea currents. The method is based on the theory of potential, eddy and wave currents. The effect of viscosity on hydrodynamic reactions is taken into account indirectly by introducing a special eddying system that simulates the effect of longitudinal vortices on the hull on the pressure distribution. The paper presents the results of a computational experiment are presented, which made it possible to identify both new and confirm previously obtained regularities of the influence of the object’s parameters and hydrophysical conditions on the desired reactions. The developed mathematical and software tool can be recommended for use in the design of underwater objects and the creation of simulators for their dynamics.
