Abstract : Rayleigh problems, in which dissociation kinetics are of significant effect, are analyzed, having in mind possible analogies to hypersonic boundary layers wit chemical nonequilibrium. The gas is imagined to be partly dissociated, initially in equilibrium, and bounded by a surface of some given degree of catalytic efficiency at the same temperature, and at rest. Then, a small change is specified to occur impulsively at the surface. The consequences of one such change, a surface temperature jump, are reviewed. Then, the problem of impulsive plate motion is treated, wherein viscous dissipation drives the gas out of chemical equilibrium, the wall temperature being held at its original level. certain implications of the study are discussed in reference to the theoretical and experimental study of hypersonic nonequilibrium boundary layers.
