Energy of inviscid incompressible fluid flowing past two equal spheres

Original language description

The aim of the work is simple formula for the kinetic energy of potential flow of an inviscid incompressible fluid past two rigid impermeable equal spheres moving arbitrarily. The kinetic energy is an essential part of equations of motions of the spheres. The energy represents an expression involving the components of the sphere velocities and the dimensionless coefficients that depend on the dimensionless distance between the spheres. The coefficients were calculated numerically by the method of successive images, which allows calculation of the velocity field as the sum of the velocity fields of sequences of dipoles located along the axis connecting spheres centers. The coefficients in the energy expression as a function of dimensionless distance between spheres were calculated as an infinite series over all the dipoles modeling the flow. The limits and accuracy are estimated from the series. The obtained dependences were fitted with high accuracy by simple continuous functions.
