The research work performed in this group, led by Prof. Zhuyin Ren is aimed at developing models and computational methodologies for the calculation of turbulent and reactive flows, especially turbulent combustion. For non-reactive turbulent flows, CFD plays an important role in the design of engineering equipment such as aircraft wings and gas-turbine compressors. While CFD is also used for turbulent combustion, the models currently in use in industry fall far short of the required accuracy and level of description. Our work is aimed at developing advanced models that provide a detailed description of the combustion chemistry and of the turbulence-chemistry interactions. This work focuses on PDF methods applied to turbulent flames; the combination of PDF methods with LES; dimension reduction and storage/retrieval methodologies for combustion chemistry; stochastic modeling of acceleration ; and turbulent mixing models in turbulent flows.
