Numerical simulation of realistic high-speed inlets using the navier-stokes equations

The tlo\v fields of two-dimensional high-speed inlets of realistic engineering geometry are solved through numerical integration of the full Navier-Stokes equations. Two inlets are considered, representative of lowaltitude acceleration and high-altitude cruise configurations. The flowfield of each is affected strongly by the curvilinear geometry and shock/boundary-layer interactions. The numerical code solves the full mean compressible Navier-Stokes equations using the algorithm of MacCormack in conjunction with a curvilinear bodyoriented coordinate system. Turbulence is represented by a two-layer eddy viscosity model. The computed results compare very favorably with the experimental data.
