Turbulent wall jets.

Abstract

Similarity analyses of the governing equations of three types of turbulent wall jet—the Radial Wall Jet, the Plane ,Wall Jet and one that is referred to as the Spherical Wall Jet—are developed.The analyses indicate how self-preserving flow can obtain in all the three cases. The Radial Wall Jet and the Plane Wall Jet have been investigated extensively and are reported to possess self -preserving flow. In the present case, a large number of mean velocity measurements have been taken in the fully developed region of turbulent Spherical il Jets. Some of these velocity profiles are presented here and are seen to exhibit similarity.
