Evaluation of inviscid/boundary layer and parabolized Navier-Stokes solutions for design of reentry vehicles

Conference ·
OSTI ID:5432858
; ;
Numerical predictions made by a traditional inviscid/boundary layer method and a parabolized Navier-Stokes method are compared with wind tunnel data for slender, blunted, cones at moderate angle of attack. Mach numbers ranged from 6 to 14 and Reynolds numbers from 0.4 to 16 million. The purpose of the comparison is to evaluate the mach number and Reynolds number range of applicability of the two prediction methods. Also described are the practical aspects of using these two methods in a design environment.
