An efficient multi-methods computer code for the prediction of the inviscid and viscous flow over multi-component airfoils

Low Mach number viscous-inviscid interaction is considered using panel methods, direct and inverse boundary layer equations. A wide variety of different panel methods and turbulent boundary layer methods are investigated to obtain the best coupling conditions for different geometries. Carter’s procedure has been used for the matching conditions in the separated regions. A computer code (MULTIM), which is fast and reliable, has been developed. Applications of the code to single and multi-element airfoils in high lift conditions are shown; the comparisons with experimental data are quite satisfactory
