ABSTRACT
The earlier Navier-Stokes (NS) analyses were performed for the forward stagnation point of flat or axisymmetric bodies using the local similarity approximation, developed by E. C. Kao for the special cases of a sphere and a cylinder. This chapter is concerned with viscous hypersonic blunt body flow studies based on the NS equations subject to boundary conditions at infinity. B. M. Pavlov integrated the full NS equations using a time-marching integration technique in conjunction with the explicit, conditionally stable finite-difference scheme of I. Yu. Brailovskaya. E. A. Gershbein and A. F. Kolesnikov obtained (numerical) stagnation region NS solutions for blunt bodies with blowing surfaces in the hypersonic rarefied-gas flow using the Dorodnitsyn coordinate transformations and the finite-difference scheme of I. V. Petukhov. The progonka method used to solve the difference equations involved iterations on nonlinearities and accounted for the mathematical nature of the singular points during the linearization procedure.
