Book Description
A Fortran IV computer program capable of calculating the radiant, viscous, nonequilibrium flow about a blunt-nosed axisymmetric or two-dimensional body is described. The program uses an iterated inverse method in the subsonic transonic region and a modification of the method of characteristics in the supersonic region. The displacement effect of the boundary layer is accounted for by a unique step-by-step method. Equilibrium radiation at the nonequilibrium temperature and composition is computed and used to calculate the radiant heating of the body nose assuming the shock layer is optically thin. An optional calculation of the effect of a magnetic field on the ionized flow in the nose region is included. The report concludes with the analysis of the nonequilibrium flow over a hemisphere cylinder at 14,000 fps. (Author).

Book Description
The volume presents information necessary for running the program discussed in Volume I. Section 1 contains information on running times, alternative versions of the program, tape requirements and remarks on built-in-options. Section 2 gives starting procedure and input format sheets. The output from the program is discussed in Section 3. Possible stops and running difficulties are discussed in Section 4. Subroutines are listed and cross-referenced in Section 5. Section 6 defines the FORTRAN symbols. The volume concludes with flow charts. (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.
