Abstract:

An IBM 709094 computer program to calculate flow properties within boundary layers, for an ideal compressible gas, was completed. The governing differential equations are approximated by an implicit finite-differencing scheme which is posed directly in nondimensionalized physical coordinates the streamwise coordinate is scaled with respect to a reference length, while the normal coordinate is so scaled and also stretched by the square root of a reference Reynolds number. The program is designed for bodies that are either two-dimensional or axisymmetric and the gas air is considered to be calorically perfect according to the equation of state, p rho RT. Initial data through the boundary layer must be prescribed, as well as the streamwise variation of pressure, and of either wall temperature, T sub w or the gradient of T sub w normal to the wall, partial T sub wpartial y. A boundary layer of zero thickness at the initial station may also be accommodated. All inputs are specified in physical coordinates. Author
