Non-equilibrium wall model for large eddy simulations of complex flows exhibiting turbulent smooth body separation
Rahul Agrawal, Sanjeeb T. Bose, Parviz Moin
In this work, a non-equilibrium wall model is proposed for the prediction of turbulent flows experiencing adverse pressure gradients, including separated flow regimes. The mean-flo…

Evaluation of eddy viscosity-based models in decaying rotating stratified turbulence
Kiran Jadhav, Rahul Agrawal, Abhilash J. Chandy
The results of large eddy simulation (LES) using three sub-grid scale models, namely: constant coefficient Smagorinsky, dynamic Smagorinsky, and a dynamic Clark model, for rotating…
