Zhongshan Li received his B.S. degree in solid-state physics and M.S. degree in infrared physics from Jilin University, China, in 1992 and 1995, respectively, and his Ph.D. degree in engineering science from Lund University, Sweden, in 2000. Since then, he has been employed by the Division of Combustion Physics, Lund University, where he is currently an Associate Professor of laser combustion diagnostics. His research interest has been focused on the development and application of advanced laser diagnostics to turbulent combustion, biomass utilization, nonthermal plasma characterization and nanoparticle synthesis. He has published more than 200 peer reviewed journal papers and has an h-index 37 in Google scholar.
Combustion in most industrial devices takes place in turbulent flow fields. The interaction between turbulence and flame dictates the overall combustion and emission behavior. The current understanding of turbulent combustion is limited to low intensity and large-scale turbulence conditions, where the molecular diffusion and chemical reactions governs the structure of the reaction zone layers. For low intensity and large-scale turbulent flames, the wrinkled and corrugated flamelet models are frequently adopted. However, modelling and understanding of high-intensity and small-scale turbulent premixed flames remain a scientific challenge. Turbulent premixed combustion has been theoretically categorized into the thin reaction zone (TRZ) and the distributed reaction zone (DRZ) regimes depending on the interactions between turbulence and flame chemistry. The presentation will describe some recent experimental efforts in exploring the interactions between turbulence and combustion via instantaneous multi-scalars imaging measurements.
