Viscid/Inviscid Interaction Analysis of Ejector Wings

Abstract

A method has been developed to predict the lift and thrust of an ejector wing by iterating between a viscous solution for the turbulent entrainment of the primary jets, and an inviscid solution for the ejector wing flow field. A two-dimensional analysis, which utilizes a turbulent kinetic energy model for the jet mixing calculation and a higher order panel method for the inviscid flow calculation, is described. The complete ejector wing geometry is analyzed. Detailed surface pressures both inside and outside the ejector can be calculated. A sample calculation for a typical ejector wing configuration is compared to experimental data.
