Experimental and Numerical Studies of Mixing and Combustion in Scramjet Combustors

A combined experimental-numerical study is under-way to validate a new large-eddy simulation (LES) for supersonic combustion studies. Experimental data on fuel-air mixing is being obtained at Georgia Tech and University of Florida while supersonic combustion is being investigated at University of Florida. The results obtained in the first year’s effort are summarized in this paper with particular emphasis on the LES model development and validation.
