THE METHOD OF CHARACTERISTICS FOR THE SUPERSONIC FLOW OF AN IDEAL DISSOCIATING GAS. 1. EQUILIBRIUM FLOW.
Abstract
The method of characteristics for the supersonic axially symmetric or two-dimensional flow of Lighthill's ideal dissociating gas under thermodynamic equilibrium is formulated, for efficient calculation, by an electronic digital computer. The equations are simplified by the introduction of the streamline slope and the cotangent of the Mach angle as independent variables. Under this transformation, the coefficients in the characteristic differential equations become rational algebraic functions. Procedures for computing the flow conditions at the next downstream interior point and for computing the next downstream point along a solid boundary, along a shock wave, and along the axis are described in detail. A complete program coded in FORTRAN for the IBM 7094 computer is listed and instructions for its use are explained. (Author)
