Authors

This research proposes new compressibility corrections for RANS models, improving turbulence prediction in low-speed and supersonic flows.

Proposed corrections significantly enhance prediction accuracy for various turbulent boundary layers and channel flows.
The method integrates variable-property corrections for wall-bounded flows with inner and outer layer scaling effects.
Modifications to the eddy viscosity improve near-wall turbulence damping due to compressibility influences.
Modeling improvements may lead to better performance in heat transfer applications and supercritical flow scenarios.
