The normal shock waves of real gases and the generalized isentropic exponents
Abstract
Two methods are outlined that can be used to calculate the normal shock wave of real gases. The first is based on an empirical observation allowing the use of the ideal gas equations describing the isentropic expansion if suitable values for the related exponents and constants are chosen. The second method approximates the behavior of the real gas by the RedlichKwong equation of state. The first method can be used if the relevant exponents are known, and the second when sufficient data for the gas are not available, and only the critical point and the heat capacity in the ideal gas state are known.
