Interaction of a free stream and a flow from a point source with dissimilar Bernoulli constants

A method for solving problems when flows with dissimilar Bernoulli constants interact is proposed. The method is used to investegate the problem of a steady plane-parallel flow of an ideal incompressible fluid around a point source from which a fluid. with a density and overall pressure, differing from the corresponding free-stream values, enters. Calculations, carried out over the whole range of variation of the governing parameter, characterizing the energy of the fluid entering from the source, demonstrate the effectiveness of the method.
