ABSTRACT

Supersonic combustion holds a great promise to revolutionize the future aviation. While this has reinvigorated the interest in this area, many challenges are foreseen in achieving this goal. The focus of this talk is on large-eddy simulation (LES) of high-speed turbulent reacting flows. Several innovative methods have been implemented to develop advanced LES software based on a “high-order spectral element method on unstructured grid” that has been developed by our research group within the last two decades. The modeling of turbulent combustion interaction is via the accurate, probability density function-based “filtered mass density function (FMDF)” method in conjunction with a Monte-Carlo solver developed specifically for our high-order flow solver. Shock discontinuities are captured using an “entropy viscosity” approach that stabilizes the solution on a coarse grid by adding artificial viscosity. Several test cases, including a ramp-cavity combustor will be presented.
