3. DESCRIPTION OF PROGRAM OR FUNCTION

PROGRAM-H was designed for the  analysis of transonic airfoils with a turbulent boundary layer correction.
top ]
4. METHOD OF SOLUTION

The analysis program with boundary layer correction is the solution of the finite difference representation of the compressible flow equations. The physical plane is mapped onto the unit circle where the difference scheme is solved using a discrete Poisson Solver for the elliptic part of the problem and a number of relaxation iterations for the entire grid. A turbulent boundary layer correction based on the work of Nash-MacDonald has been incorporated into the program. It is solved iteratively with the flow calculations.
