Predictions of flow distortions inside a serpentine diffuser from large-eddy simulations
Rahul Agrawal, Chad Winkler, Sanjeeb Bose +1
This work examines the flow separation and the resulting pressure distortions at the exit plane of a serpentine diffuser operating at both subsonic and transonic conditions. Wallmo…

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…

Studies of Transonic Aircraft Flows and Prediction of Initial Buffet Onset Using Large-Eddy Simulations
Konrad A. Goc, Rahul Agrawal, Sanjeeb T. Bose +1
This article utilizes the Large-Eddy Simulation (LES) paradigm with a physics-based turbulence modeling approach, including a dynamic subgrid-scale model and an equilibrium wall mo…
