HYDRODYNAMIC INTERACTION BETWEEN BODIES IN A PERFECT INCOMPRESSIBLE FLUID AND THIER MOTION IN NONUNIFORM STREAMS

A general method based on the use of Lagrangian equations for determining hydrodynamic interaction between bodies in a fluid is presented. Formulas for the kinetic energy and the Lagrangian function are reduced to a form which permits an effective application of the method of small parameter. Additive components of kinetic energy and of the Lagrangian function, which determine the hydrodynamic interaction between two bodies, one of which is small in comparison with the distance between the two, are calculated. The method is used for considering the case of several bodies. The results are expressed in terms of coefficients of apparent mass of individual bodies in a boundless fluid. General formulas are derived for forces and moments acting on a body in a nonuniform stream.
