The simulation and modeling of turbulent flows

Professor Krishnan Mahesh, University of Minnesota

Our group at the University of Minnesota focuses on fundamental advances in numerical algorithms, and understanding of flow physics that allow the prediction of engineering turbulent flows.  This presentation will discuss key aspects of such simulation alongside illustrative examples. Special attention has been paid to ensuring robustness and accuracy at high Reynolds numbers without numerical dissipation. The basic ideas behind this methodology will be discussed. The predictive capability of LES will be demonstrated for complex problems; e.g. propeller crashback and cavitation. LES results will be shown to be in good agreement with experiments and used to discuss aspects of the underlying physics.
