Using WMLES, this study compares the differences between free-air and National Transonic Facility (NTF) environments on the CRM-HL. Findings reveal significant aerodynamic discrepancies at lower Reynolds numbers, where tunnel effects trigger earlier stall. However, increasing the Reynolds number reduces the variance between environments.
