Abstract
The focus of this project is on large-eddy simulation (LES) of high-speed turbulent reacting flows. The Enabling Energy Systems (EES) Inc. has assembled a well-experienced team of experts to tackle all the main issues involved in modeling of such complex flows. Several innovative ideas have been proposed and team members have complementary expertise. The ultimate goal of the project is to develop advanced LES software based on a"high-order spectral element method on unstructured grid"that has been developed by the PI"s group within the last decade. The modeling of turbulent combustion interaction will be via the accurate, pdf-based,"filtered mass density function (FMDF)"method that has been developed, implemented, and tested for subsonic flows by Professor Jaberi"s group at Michigan State University. MSU will be one of the subcontractors on this project and will help EES to implement and test FMDF in the spectral element code for high-speed flows. Shock discontinuities will be captured using an"entropy viscosity"approach that will be developed by Professor Jacobs for our spectral method. Professor Jacobs has extensive experience with spectral methods and will also serve as a subcontractor. Phase I results have provided the proof of concept for all these methods.
