Abstract:

This paper first derives a set of basic formulae of varying specific heat oblique shock waves. For various fundamental problems of solving turn angle,shock angle, maximum wedge angle and minimum Mach number of shock attachment, analytical methods are proposed with illustrative examples. Thus the analytical solution of varying specific heat oblique shocks has been commenced without much difficulty, nevertheless, further deepening problems remain to be tackled.
