Modeling of Transition Effects in Hypersonic Intake Flows Using a Correlation-Based Intermittency Model

Abstract

Within the frame of the GRK 1095 (Research Training Group) ”Aero-thermodynamic Design of a Scramjet Engine for Future Space Transportation Systems” a numerical and experimental analysis of a scramjet intake has been initiated at RWTH Aachen University. The paper presents an overview of the ongoing work on the numerical simulations using a well validated Reynolds averaged Navier Stokes solver, namely QUADFLOW. For the simulations the γ-Reθ model proposed by Langtry/Menter 1, 2 extended with in-house correlations for onset and length of transition is applied. For validation purpose, several simulations of subsonic flat plate flows and hypersonic double ramp configurations have been performed. The validation with respect to scramjet intakes is done by comparing the numerical results of this paper to experimental results of DLR Cologne.
