Abstract

A vortex analog is found for a potential three-dimensional source. The possibility of extending the known method of superposition to the case of axisymmetric vortex flows is indicated. Considered as an illustration is the axisymmetric homogeneous helical flow around a half-body. It is shown that the pressure is constant in an axisymmetric vortex stream without a circumferential velocity.
