Abstract

Results are present here for viscous transonic flow over aerofoils to demontrate the capabilities of a code based on transonic full potential equation in a system of cartesian coordinates has been written incorporating many improvements apart from incidentally enchancing its computational efficiency. Thus the improvements in the numerical implementation of the surface boundary condition renders the code tobust resulting in an enhanced N-a domain in which accurate result can be obtained from the code, further Green's log entrainment method is used along with transpiration model to include viscous effects due to aerofoil and wake. An empirical procedure is included to make the drag calculation more realistic. A viscous reap model is incorporated to enable cases of strong shock boundary layer interations to be computed. The code has been validated extensively against experimental results.
