Numerical investigations in three-dimensional internal flows

In order to develop an understanding of flow fields that exist in sidewall compression inlet models, an explicit, time-accurate full Navier-Stokes code was used to model them. Both laminar and turbulent boundary layers were numerically simulated. These simulations were examined as they were influenced by Mach number, changes in sidewall compression angle, hypersonic viscous interaction effects, and thick entering boundary layers. Cause and effect relationships were established. The numerical simulations were compared with the limited data available to aid in understanding both the simulations and the experiments.
