Viscous/inviscid analysis of curved sub- or supersonic wall jets

T features of a viscous/inviscid curved wall jet model, under development for application to the analysis of circulation-controlled airfoil flowfields, are described. The model solves the surface-oriented parabolized Navier-Stokes equations using pressure-split methodology for subsonic wall jets and shock-capturing methodology for supersonic wall jets. A hybrid two-layer turbulence model is employed that combines a damped VanDriest inner layer formulation with a curvature-corrected, two-equation ke model outer region formulation. Procedures for performing the strongly interactive coupling of the wall jet solution with an external potential flow solver are discussed. Preliminary calculations for simple wall jets are shown to compare quite favorably with both mean flow and turbulent measurements.
