Determination of Interaction Forces in the Problems of Dynamics Of a Floating Body containing Liquid Charges

摘要

A problem on the motion of the vessel with liquid charge as a freely floating body with six degrees of freedom is considered in nonlinear statement. In mobile Cartesian system of coordinates invariably connected with a solid body the author formulates the internal and external nonlinear boundary-value problems on movement of ideal noncompressible liquid in a supposition on potential character of flows. General formulas are obtained to determine forces of interaction between the vessel case and liquid. The formulas are obtained on the basis of the introduced most natural division of rate potentials of unbounded external and bounded internal volumes of liquid for the components.
