Abstract:

The report describes a Fortran IV computer program which calculates supersonic flow fields with viscous effects. The code is based on a Lagrangian finite-difference technique in which the computational grid is composed of streamlines and the surfaces orthogonal to them, and can be applied to two-dimensional or axially symmetric flows. Viscous transport in the direction normal to streamlines is included. Diffusive effects are treated with the full multicomponent and pressure diffusion formalism thermal diffusion is treated approximately. Boundary conditions which may be treated include solid walls, free boundaries at given pressures, free boundaries with Newtonian impact pressures, or shocks propagating into known external flows. Multiply shocked flows may be treated by successive runs of the program. Instructions for preparing input to the program are given. Sample inputs for several different types of flow are presented, together with results of the calculations at a few downstream locations. Author
