Pagination or Media Count:
The report contains a numerical program for solving hydrodynamic flow and radiation transport problems in the diffusion and grey-body approximations. The program is appropriate to the solution of explosion and shock wave problems, and to the study of high explosive or nuclear fireballs, hot gas dynamics, deflagrations and detonations, bubble phenomena, shock tube flows, and can be adapted to a host of other dynamics problems. It is restricted to plane, cylindrical, or spherical symmetry. The report offers 1 a description of the assumed physical model, 2 a rationale for the difference equations and integration techniques used in the mathematical formulation, 3 a complete set of flow diagrams for the program and its subroutines, 4 a listing of the code, 5 two illustrative example calculations for hydrodynamics and for radiation flow, and 6 helpful hints for checking and running versions of the program.
