Combat aircraft configurations typically feature low aspect ratios and highly swept leading edges in order to provide the required agility. At extreme flight conditions, complex flow fields dominated by vortex systems, which are challenging for numerical flow simulations, are generated. A major challenge in computational fluid dynamics is to model turbulence in order to correctly produce flow physics. ​ The complex turbulence fluctuations in the flow field are captured by the underlying turbulence models​.  A newly developed model, which is capable of predicting flows dominated by leading-edge vortices in a time-efficient and yet accurate manner, should be provided in the end.
