Evaluation of Local Effects of Transitional Knudsen Number on Shock Wave Boundary Layer Interactions

The influence of the local effects of rarefaction on the prediction of the main parameters typical of Shock Wave - Boundary Layer Interaction are presented and analyzed. Slip flow boundary conditions have been implemented in CIRA CFD code H3NS, and results have been compared with available wind tunnel experiments and DSMC results. Finally, an experimental wind tunnel test case, planned in CIRA Plasma Wind Tunnel facility, has been analyzed in order to check possible local effects of rarefaction.
