TRANSITIONAL FLOW ANALYSIS OVER DOUBLE COMPRESSION RAMP WITH NOSE BLUNTNESS IN SUPERSONIC FLOW Shin, Ho Cheol; Sa, Jeong Hwan; Park, Soo Hyung; Byun, Yung Hwan;
Accurate prediction of supersonic transition is required for the heat transfer estimation over supersonic double compression ramp flows. Correlation-based transition models were assessed for a supersonic double ramp problem. Numerical results were compared with experimental data from RWTH Aachen University. A parametric study on the nose bluntness was performed using a selected transition model. As the nose bluntness increases, the boundary layer thickness is increased and the triple point of shock interactions moves downstream. The peak magnitude of the heat transfer is consequently decreased with the nose bluntness.
