The assessment of an adaptive turbulence model based on the Spalart-Allmaras turbulence model will show improved results for common (U)RANS CFD simulations for leading edge vortex dominated flows. This simple model improvement can cut computational cost, time, and energy during aircraft design phases, since more relatively low-cost simulations at higher levels of accuracy can be conducted.
