Turbulent Combustion Laboratory

Research themes: Professor Tong's research on turbulent combustion focuses on subgrid-scale mixing and turbulence-chemistry interaction, especially on the SGS physics related to filtered density function methods for large-eddy simulation of turbulent combustion. Student using lab equipmentHe made the first measurement of the filtered density function, discovering two limiting SGS mixing regimes, which have important implications for developing mixing models capable of predicting all combustion regimes. He has been exploring a new modeling framework and studying physics within this framework.

Lab facility/equipment: The Turbulent Combustion Laboratory is a facility for making measurements of turbulent flames. It consists of a flame facility and a laser diagnostic system. View of inside the turbulent laboratoryThe former includes air and gas supplies, an open wind tunnel, a burner, and an exhaust system. The latter consists of a 266 nm 250 mJ/pulse Nd: YAG laser and a 298 nm dye laser and the 532 nm pump laser for laser-induced fluorescence imaging, a 532 400 mJ/pulse Nd: YAG laser for Rayleigh scattering imaging, a 350 mJ//pulse double-pulse Nd: YAG laser for particle-image velocimetry, and several regular and intensified CCD cameras. The facility can also be used to conduct experiments in non-reactive flows.
