THE PLANE LAMINAR JET.

Abstract

The plane laminar jet emanating from a point orifice is considered. The method of matched asymptotic expansions is used to determine higher-order 'inner' and 'outer' solutions, which are valid at some distance from the orifice. It is shown that the first-order 'inner' solution is non-unique, with respect to a small perturbation, and introduces an arbitrary constant. Higher-order solutions are obtained and the existence of additional arbitrary constants is predicted. It is seen that although axial viscous effects do not appear to second-order, the downstream momentum flux is variable due to a non-uniform pressure distribution. (Author)
