Abstract
Ensuring static stability of the flame is of utmost importance in augmentor systems. It is proposed to develop an optimum set of models that will numerically simulate turbulent combustion in augmentors and help in the detailed understanding of the physical processes affecting the static stability of the flame. Research will be done on scalar mixing models for scalar variance and dissipation rate for multiphase flows, modification and updating of available chemistry models to include auto-iginition chemistry, combination of unsteady flamelet/progress variable (UFPV) and level set methods to capture both premixed and non-premixed regions in the augmentor, and the formulation of all these models for compressible flows. The entire development and all the computations will be performed in a large eddy simulation (LES) setting. The complete suite of the models will be extensively tested and validated against experiments in a wide range of operating augmentor conditions. For this, an experimental configuration will be chosen in collaboration with our industrial partners and successive LES computations will be performed and the results compared against the experimental data for continued development of the chosen models.
