FIRST ORDER SLIP EFFECTS ON THE PLANE COUETTE FLOW OF A DISSOCIATING GAS,
Abstract
An analysis is made of the first order slip effects on the skin friction and heat transfer of a parallel flow of a reacting gas next to a catalytic surface at which atom recombination and slip occur. Calculations were made for oxygen for three limiting cases - equilibrium flow, frozen flow with a fully catalytic wall. It was found that the presence of slip reduces the ratio of Stanton number to friction coefficient in all cases, but causes an increase rather than a decrease in skin friction at high free-stream temperatures or velocities. This is due to the fact that the temperature jump and change in atom concentration at the wall increase the viscosity by a larger amount than the presence of slip reduces the wall velocity gradient.
