A numerical solution to the boundary layer equations for dissociated air
The boundary layer equations for a quasi-equilibrium flow of dissociating air past a flat plate have been solved on an electronic digital computer. The solution is based upon a modification of Crocco's method, which takes into consideration the variation of the Prandtl, Schmidt and Lewis numbers. …
