Abstract
A study is made of a chemically nonequilibrium flow in local regions near cold walls. It is found that in this case the chemically reactions can take place only on a catalytic surface, and the gas can be regarded as a binary mixture of atoms and molecules. As an example, a study is made of the aerodynamic heating of a small step on the surface of a plate in the case when the flow past the plate is described in the first approximation when the Reynolds number tends to infinity by the Navier-Stokes equations for an incompressible gas. It is found that the presence of the step increases the drag of this section of the body, for a noncatalytic surface leads to an additional heating of it, and for a catalytic surface weakens its catalytic activity and, therefore, reduces the heating of the step.
