Abstract

The stick-slip problem for a round jet is solved in two ways: by a Wiener-Hopf method and by a direct method in which eigenfunction solutions in the pipe and jet are matched on their common boundary. The same solution is obtained by the two methods, but the eigenfunction method is more direct and converges more rapidly. Reliable graphs are presented for the distributions of the velocity components, stresses and pressures at different axial positions in the pipe and jet. The shape of the free surface for the low speed jet is computed by a perturbation method.
