Abstract

The application of the unstructured mesh system FLITE3D.0 to the numerical analysis of the inviscid Euler flow past installed aero-engine nacelle is described. The main features of the system are detailed and the approach is demonstrated by simulating the flow over a Rolls-Royce model of a twin-engined civil transport aircraft with long-cowl nacelle powerplants. The computed pressure distributions are compared with the measurements produced by transonic wind tunnel experiments.
