On submerged jets
A non-similarity, axisymmetric, and in general twisted jet of incompressible fluid, flowing from a spherical source into a submerged space, is considered. It is shown that the solution of this problem is not expressible by a series of integral inverse powers of the spherical radius R, but has an essentially singular point at \(R=\infty\). The principal terms of the asymptotic expansion are given by four integrals of conservation, namely, momentum, flow rate, and two components of angular momentum, and not by three.
