A detailed analysis is carried out on a rectangular scramjet inlet to analyze the flow field. The focus is on examining boundary layer separation and shock interactions to ensure proper operation of the inlet. We developed herein a flux-splitting Navier Stokes solver to be used for optimizing the inlet geometry and operation conditions. The results seem to be in good agreement with that of FLUENT CFD software and explain the experimental results of Haberle (2008). Copyright © 2010 by ASME. Source

The objective of this work is to develop a simulation procedure for prediction of micro thermo-fluid transport through porous materials. Emphasis is placed on the prediction and optimization of the heat transfer process in the Knudsen number range wherein the continuum slip-flow hypothesis is valid. We developed herein a large-scale simulation code for the heat transfer between two fluids separate by porous surface as a simplified model of transpiration cooling in turbine blades. Results indicate that the heat transfer rate is optimum at certain values of the slip coefficient. Copyright © 2010 by the American Institute of Aeronautics and Astronautics, Inc. Source
