Abstract

NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document.

The viscous hypersonic flow past an axisyrnmetric blunt-body is analyzed based upon the Navier-Stokes equations for a perfect gas having constant specific heats, a constant Prandtl number, P, whose numerical value is of order one, and a viscosity varying as a power, [...], of the absolute temperature, as the free-stream Mach number, M, and the freestream Reynolds number based on the body nose radius, R, go to infinity, and [...] (where [gamma] is the ratio of the specific heats) and [...] go to zero.

Through the use of strict asymptotic expansions, the behavior of the flow in the three distinct regions that comprise the interior of the "shock structure" is found, as well as for the one, two, or three regions that make up the "shock layer" depending on whether the quantity [...] is equal to [...], equal to [...], or greater than [...], respectively.
