A Program for Calculating Radiation Flow and Hydrodynamic Motion
A numerical program is presented for solving shock wave and fluid dynamic problems in the presence of radiation flow, which can be adapted to a wide range of dynamci problems. The program is Lagrangian in approach and is capable of calculating hydrodynamic motions, including shocks, in one space dimension: spherical, cylindrical, or plane symmetry. Radiation diffusion, grey-body or other radiation losses, and energy sinks or sources are simultaneously calculable with this code. The study describes the physical models that can be called upon in solving various problems, displays the consequent differential equations, and develops the difference methods employed in the step-wise integration. A variety of initial problem desscriptions and boundary conditions can be called upon. Outputs can be in a selected listing or can be taped for automatic plotting and further processing. An all-FORTRAN version is featured as being useful on the widest variety of computing equipment, and a listing of the complete program is supplemented by flow diagrams, example calculations, and suggestions on setting up and running problems.
