Nonequilibrium Laminar Boundary Layer Flow of a Binary Gas,

Abstract

The non-equilibrium boundary layer is considered as a binary mixture of atoms and molecules with finite rates of dissociation and recombination. To obtain accurate ullutions to the partial dif ferential equations for this type of flow without any necessary simplifying assumptions, an im plicit finite-difference scheme is developed for solving these equations with a digital computer. Accurate solutions to the non-equilibrium bound ary layer equations have been obtained in a reasonable amount of computer time and are pre sented for a flat plate, cone, and hemisphere cylinder. The results show that the non equilibrium boundary layer temperature and com position can be considerably different from local equilibrium and frozen results. For a cone at 21,000 ft/sec and 100,000 ft. altitude, the computations show that at 60 ft. from the tip the flow has not reached equilibrium. (Author)
