Professor in the Department of Aerospace Engineering and Mechanics at the University of Minnesota
Will present a talk titled:
Large Eddy Simulation Applied to Marine Problems
Abstract:
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 in marine flows. 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. flow over appended hulls, propeller flow under both design and off-design, and cavitation. LES results will be shown to be in good agreement with experiments and used to discuss aspects of the underlying physics.
