Description

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. The members of this team are proposing several innovative ideas and have a long history of working together with 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 combustion modeling 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 the main subcontractor on this project and will help EES to implement and test FMDF in our 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 serve as a consultant. Several tests have been identified to validate the software.
