Space flow geometry of the radial free, wall and liquid jets with swirl

Abstract

A detailed similarity analysis of the incompressible radial free, wall, and liquid jets with swirl is presented. The analysis aims at a determination of the space flow geometry of the given generally formulated problems. The derived space flow geometry implies that the transformed formulations of the given problems are formally identical to those without swirl. Unlike the free jet, the wall and liquid jets with swirl are treated only for a Newtonian fluid but in this case the similarity analysis also provides the interpretation of a virtual origin.
