Jim Kok received his MSc degree in Mechanical Engineering in 1985 at the University of Twente (Enschede, NL) in the group of Fluid Mechanics and Heat Transfer. Subsequently he obtained his PhD degree at this university in 1989 on the subject of "dynamics of gas bubbles moving through liquid". Subsequently he became a member of faculty. He performed research on turbulent combustion with application on gas turbine engines. Before 2000 the focus was on reduction of nitric oxide emission, but since then the interest focused on the interaction of combustion dynamics and acoustics and engine design and operation. The work involves both CFD modeling and experiments.His teaching includes courses on turbulent combustion theory, modeling and analysis for gaseous fuels and liquid fuels.

Research covers the fields of combustion dynamics, acoustics, heat transfer and thermodynamics. In numerical methods a compressible non-adiabatic reaction progress variable combustion model was developed that can be applied on turbulent flows with LES or RaNS approach. The experimental research includes work on an atmospheric combustor in limit cycle oscillation and a pressurized combustor using laser diagnostics and multi microphone techniques. Specific applications studied are gas turbine engine power generation and propulsion. The main theme is pressurized and atmospheric combustion of sustainable fuels in gas turbine (aero) engines and furnaces and boilers. Fuels can be low calorific gases, NH3, H2 of jet fuel. Important phenomena studied are combustion stability, transient combustion behavior and emission of toxic species
