Book Description
The method of characteristics equations for twodimensional or axisymmetric non-equilibrium real gas flow is formulated for machine computation. The basic equations were derived assuming rotational, inviscid flow of a reacting multi-component gas. An approximate model of dissociated non-equilibrium air is presented which is ideal for use with the method of characteristics. Results from a simple one-dimensional program which uses this model of air compare very closely with results from a program which uses a much more sophisticated model. (Author).

Book Description
The method of characteristics is formulated for the computation of the supersonic flow of an inviscid, reacting gas over a smooth three-dimensional body. Various methods of constructing networks of bicharacteristic lines are examined from the point of view of numerical stability and accuracy. A new method of forming the network, which consists of projecting forward along streamlines from data points on specified data planes, is found to be most easily adopted to the particular requirements of nonequilibrium chemistry. The general method was coded for the IBM 7090 computer and the program demonstrated for the case of an ideal gas. Calculations were made for the case of an ideal gas. Calculations were made for the flow about a spherical-tip 15 degree half-angle cone at 10 degree angle of attack and a generalized elliptical body at zero incidence. Since the program yields the pressure distribution along specified streamlines, it is straightforward, in principle, to link it to a finite-rate chemistry stream tube program to treat three-dimensional, nonequilibrium flows.

Book Description
This document presents a summary of results from a digital computer program for calculating inviscid supersonic flow fields around two-dimensional bodies or axisymmetric bodies at zero angle of attack. This program, based on the method of characteristics, can be used for either perfect or real gas in thermodynamic equilibrium and can calculate flow fields around bodies with flares or concave curvature. Results are presented for both sharp and blunt nosed bodies in perfect and real gas. Whenever possible, they have been compared with experimental data. (Author).
