The dissociative relaxation in a viscous shock layer of iionequilibrium dissociating diatomic gas in the stagnation region of a blunt hypersonic body is analyzed. The case in which the maximum local dissociation level is appreciably lower than the inviscid equilibrium value is considered. A simplified atom concentration equation is derived neglecting the recombination term in the reaction, and it is solved for a range of conditions using a digital computer. The procedure for determining the stagnation-point wall concentration for the general case of arbitrary freestream and wall conditions, including air, using the result of these solutions, is described. The approximate solution based on the simplified concentration equation is compared with the exact solutions and shown to agree approximately when the maximum dissociation is less than 80% of the inviscid equilibrium value.
