Fellowships for the Advancement of Large-Eddy Simulation

Abstract

In many complex flows, large-eddy simulation is difficult due to the simultaneous presence of a variety of flow features, often with quite different resolution requirements. For this reason, unstructured-grid large-eddy simulation techniques are being developed using the finite element method to solve the compressible Navier-Stokes equations with a dynamic model of the subgrid-scale stresses. As the purpose of this report was to support graduate student education, the bulk of this report is taken from the work of the student supported by this research (Andres Tejada-Martinez). That student has focused on the characterization of filters used within the dynamic subgrid-scale model for large eddy simulation. Though he is not quite finished, this report clearly shows that much was learned under the three years of support by the AFOSR.
