BOUNDARY CONDITIONS AT THE OUTER EDGE OF THE BOUNDARY LAYER ON BLUNTED CONICAL BODIES

Abstract

Abstract : A method for predicting the variation of Mach number that prevails at the outer edge of the boundary layer of a blunt conical body is presented. The method consists of solving the mass flow equation as given by the similar solutions of Lees. The mass flow equation is integrated and an expression for the distance where the local Mach number reaches the conical value is given. In the analysis, the static pressure isASSUMED TO BE CONSTANT OVER THE ENTIRE PORTION OF THE CONE, AND THE PROPERTIES AT THE OUTER EDGE OF THE BOUNDARY LAYER ARE CALCULATED FROM THE FINAL SOLUTION. Finally, the analysis is compared with some of the experimental results available in the literature. It is indicated that good agreement was obtained for this comparison. (Author)
