About the Lab

Professor Ock Chae Kwon's research lab specializes in fundamental combustion science, with a focus on laminar premixed flame dynamics, flame stability, and the effects of stretch on flame propagation. The lab conducts detailed experimental investigations on unstretched laminar burning velocities and flame response to stretch (Markstein numbers) in various hydrocarbon-air mixtures under controlled conditions. Their work contributes significantly to the understanding of flame behavior in internal combustion engines and industrial burners, particularly under variable pressure, equivalence ratio, and oxygen concentration. The research also explores the flammability limits and combustion characteristics of alternative fuels such as alcohols and hydrocarbons.

Unstretched laminar burning velocities and e ame response to stretch (Markstein numbers ) were measured for outwardly propagating spherical laminar premixed e ames involving mixtures of hydrocarbon vapors, oxygen, and nitrogen. Experimental conditions consisted of vapors of several liquid fuels (n-hexane, n-heptane, iso-octane, methyl-alcohol, and ethyl-alcohol ), concentrations of oxygen in the nonfuel gases of 19 ‐33% by volume, pressures of 0.5‐2.0 atm, fuel-equivalence ratios of 0.80 ‐1.60,
