Abstrakt

Two component, laminar boundary layers on a surface with zero pressure gradient, including the effects of variable properties, are studied. Hydrogen is injected from the stationary, porous flat plate into a free stream of nitrogen or carbon dioxide. The two situations treated are the constant wall temperature and the adiabatic wall. The Mach numbers considered are 0, 4, 8, and 12, the free stream temperature t ranges from 218°K to 1110°K and the wall temperature to free stream temperature ratio Tw = tw/t ranges from 0.5 to 6. In addition to velocity, concentration and temperature profiles, the heat transfer and skin friction are also obtained. The final results are presented in simplified curves which are useful for design calculations.
