A turbulent combustion subgrid model, inspired by the Linear Eddy Model for Large Eddy
Simulation (LEM-LES), is developed to study highly compressible and reactive flows
involving very rapid transients in pressure and energy. The model is intended to be a one-
dimensional treatment of a diffusion-reaction system within a multi-dimensional LES cell.
