This paper is an extension of the previous paper⁵⁾, and analyzes the inviscid hypersonic vibrational nonequilibrium flow in the shock layer about the stagnation region of a blunt body generating a spherical shock wave. With the assumptions of thin shock layer, strong shock and constant relaxation time, expressions for the temperature, internal energy and density are derived. These expressions have been evaluated for a sphere for various shock radius, ranging from near equilibrium to near frozen flow. Comparison of the calculated temperature distribution with those based upon a numerical solution shows reasonable agreement in near equilibrium flow.
