Dr. Joohan Kim is a research scientist in the Multi-Physics Engine Computation Section in the Transportation and Power Systems Division. His research interests lie in multi-dimensional computational fluid dynamics (CFD) modeling of ignition, combustion, and pollutant formation processes in various propulsion systems, such as internal combustion engines, combined heat and power systems, and conventional and advanced ignition systems.

At Argonne, Dr. Kim has extensively investigated turbulent jet ignition (TJI) processes in pre-chamber (PC) engines under different PC operation modes and dilution strategies. Also, he developed a CFD model for simulating nanosecond-pulsed discharge ignition and its flame kernel evolution, for which he used a multi-dimensional thermal plasma solver to obtain accurate plasma properties. He received both Argonne’s Impact Argonne Award for Notable Achievement through Extraordinary Effort and Argonne’s Postdoctoral Performance Award in the area of Engineering Research in 2021.

Dr. Kim received his Bachelor’s degree and Ph.D. in Mechanical and Aerospace Engineering from Seoul National University (South Korea).
