ON THE MIXING OF LAMINAR AND TURBULENT AXIALLY SYMMETRIC COMPRESSIBLE FLOWS,

Abstract

A unified analysis to solve mixing problems in volving momentum, energy, and mass transfer in both laminar and turbulent axially symmetric compressible flow is presented. The method is based on the linearization of the conservation equations in the plane of the von Mises varia bles while retaining the essential nonlinear nature of the equations in the physical plane. The application of this method to a laminar flow problem is shown to be in good agreement with a numerical solution of the boundary layer equa tions obtained by Pai. The application of this method to turbulent flow requires an expression for the eddy viscosity. Prandtl's formulation has been applied successfully to problems involv ing incompressible flow. To allow for compressi bility effects, a possible modification of Prandtl's formulation, suggested by Ferri, is in vestigated. When this expression for eddy vis cosity is introduced, the application of the present method to compressible turbulent flow yields analytical results which are in good agreement with available experimental data.
