My primary research area is turbulent combustion modeling. I have developed a numerical model for predicting combustion characteristics and emissions inside diesel engines by applying the Conditional Moment Closure (CMC) model, a conditionally averaged model for turbulent diffusion flames, to a multizone model. Additionally, I have conducted numerical studies on the combustion characteristics of turbulent premixed flames, including turbulent burning velocity. Recently, I have been conducting experimental research on alcohol fuels in diesel engines to explore the feasibility of alternative fuels and have also validated various chemical mechanisms. Furthermore, I developed a 1D combustion diagnostic model for reheating furnaces in steel mills.
