THE COMPUTATION OF OBLIQUE SHOCK WAVE CHARACTERISTICS FOR REAL GASES,
Abstract
A method is presented whereby oblique shock wave data for real gases may be readily obtained from real gas normal shock wave data corresponding to the same upstream thermodynamic state. Although such solutions are well known for perfect gases there appears to be no method available at this time to account for real gas effects. This method is only useful when the flow deflection angle is the specified parameter instead of the wave inclination angle. There is no restriction to any gas com position since the physics of the problem are completely contained in the normal shock characteristics. It is expected that primary use of this method will be found in the study of vehicles for entry into planetary atmospheres. Because of the present uncertainty of the characteristics of any of the planetary atmospheres it is not economically justifiable to compute oblique shock charts for every conceivable model atmosphere. However, to even begin consideration of an entry vehicle requires that some normal shock computations be made. (Author)
