Abstract:

A method for solving general compressible three-dimensional boundary-layer flows is developed. The equations are initially placed in a Crocco-type form which makes use of similarity variables. A general solution tehcnique which employs an implicit finite-difference scheme that is stable for negative transverse velocities is developed. As an application of the method, solutions for 10 degree vertical half-angle elliptical cones of varying ellipticity ratios at up to 8 degree angle of attack at a Mach number of 7.95 are presented. Skin friction and heat-transfer-rate distributions are presented for all cases. Good agreement is found with the experimental data of Tracy for heat-transfer rates on circular cones at angle of attack. Author
