  • Viscous‐inviscid interaction is used to compute steady two‐dimensional, transonic flows for solid and porous aerofoils. A full‐potential code was coupled with both a laminar/transition/turbulent integral boundary‐layer/turbulent wake code and the finite‐difference boundary‐layer code using the semi‐inverse methods of Carter and Wigton. The coupling was performed using the transpiration coupling concept, thus allowing for analysis of porous aerofoils with passive physical transpiration. The computations confirm experimental findings that passive physical transpiration can lead to a lower drag coefficient and a higher lift coefficient, a weaker shock and elimination of shock‐induced separation. Nevertheless, it is very important that the extent of the porous region and permeability factor distribution of the porous region are chosen carefully if these improvements are to be achieved.
