Code to code comparison on hypersonic high enthalpy transitional boundary layers

Wartemann, Viola and Wagner, Alexander and Wagnild, Ross and Pinna, Fabio and Miro Miro, Fernando and Tanno, Hideyuki (2018) Code to code comparison on hypersonic high enthalpy transitional boundary layers. AIAA SciTech, 8–12 January 2018, Kissimmee, USA.

Full text not available from this repository.


In the present study three boundary layer stability codes are compared based on hypersonic high enthalpy boundary layer flows around a 7° blunted cone. The code to code comparison is conducted between the following codes: the NOnLocal Transition analysis code (NOLOT) of the German Aerospace Center (DLR), the Stability and Transition Analysis for hypersonic Boundary Layers code (STABL) of University of Minnesota and the VKI Extensible Stability and Transition Analysis code (VESTA) of the von Karman Institute. The comparison focuses on the role of real gas effects on the second mode instability, in particular the disturbance frequency. The experimental test cases for the code to code comparison are provided by the DLR High Enthalpy Shock Tunnel Göttingen (HEG) and the JAXA High Enthalpy Shock tunnel (HIEST).
