Theoretical Solutions for the Secondary Flow on the End Wall of a Vortex Tube

Abstract

All theoretical solutions obtained are based on assumed shapes for the tangential and radial boundary layer velocity profiles and assumed laws relating the tangential and radial wall friction to the Reynolds number of the flow. Sample calculations for the variation with radius of tangential velocity, boundary layer weight flow, and boundary layer thickness for a laminar boundary layer profile and friction law are given for both strong-vortex and weak-vortex cases, whereas numerical examples for a turbulent boundary layer profile and friction law are given only for the strong-vortex case. The accuracy of results calculated from the theory should be limited only by the accuracy of the velocity profiles and shear formulas used in the calculation procedure.
