Research Interests

​Professor Im’s research interests are primarily fundamental and practical aspects of combustion and power generation devices using high-fidelity computational modeling. Recent research topics combustion characteristics of high hydrogen content fuels, advanced modeling of sooting flames, modeling of mixed-mode combustion in modern engines, dynamics of turbulent premixed flame propagation, turbulent flame stabilization, spray- and particle-laden flows and combustion, plasma and electric field effects on flames and combustion of low-grade fuels.
