Description	Cílem práce je obdržet jednoduché rovnice kinetické energie proudu ideální kapaliny obtékající stejné dvě tuhé volně se pohybující koule. Energie je dána výrazem zahrnujícím složky rychlosti koulí a bezrozměrný součinitel, závislý na bezrozměrné vzdálenosti obou koulí. Pro numerický výpočet byla použita metoda zobrazení a získané závislosti byly s vysokou přesností aproximovány jednoduchým spojitými funkcemi. Rychlostní pole kapaliny bylo vypočteno sumací rychlostních polí řady dipólů, umístěných podél osy válcové symetrie koule-koule. (cs) The aim of this work is to obtain a simple formula for the kinetic energy of the flow of an ideal incompressible fluid past two rigid arbitrarily moving equal spheres. The energy represents an expression involving the components of the sphere velocities and the dimensionless coefficients depending on the dimensionless distance of the spheres. The dependencies were calculated numerically using the image method and were fitted with high accuracy by simple continuous functions. The fluid velocity field was computed as the sum of the velocity fields of sequences of dipoles located along the axis of sphere-sphere cylindrical symmetry.
