  • The gas temperature within hypersonic boundary layer flow is so high that the specific heat of gas is nolonger a constant but relates with temperature. How variable specific heat to influence on boundary layer flow stability is worth researching. The effect of the variable specific heat on the stability of hypersonic boundary layer flows was studied and compared with the case of the specific heat to be supposed constant, based on the liner stability theory. It is found that the variable specific heat indeed has some effects on the neutral curves of both first-mode and second-mode waves, and on the maximum rate of growth either. Therefore, the relation ship between specific heat and temperature should be considered in the study of the stability of the boundary layer.
