Summary

A simple method for computation of the flow on airfoils has been developed to help in the development of suitable profiles for turbulence manipulation1. Typically these will have chord Reynolds numbers of 300,000 or less, be located in a high subsonic or transonic Mach number boundary layer close to a wall. The analysis does not require a good prediction of maximum lift, but instead must be able to describe flow properties and drag adequately within a CL-range. Since a large number of parameters are involved, and since the turbulence manipulation to a large extent depends on the dynamics of the flow on and behind the profiles, it was necessary to establish a code that was direct, fast, and allowed computation of a typical characteristics in a matter of minutes on a minicomputer or a personal computer.
