Ben Akih-Kumgeh

Degree(s):

  • Ph.D., McGill University

Lab/Center Affiliation(s) (i.e. CoE or SBI):

  • Center of Excellence

Research Interests:

  • Combustion physics and chemistry (chemical kinetics, ignition, flame propagation, extinction, and pollutant formation, turbulent combustion)
  • Applied combustion in gas turbines, internal combustion engines and process burners
  • Fuel technology (formulation, additives and characterization)
  • Thermodynamic analysis of energy systems

Current Research:

Our research interests are in the area of energy conversion, with a special focus on Combustion Physics and Chemistry. Our work is a combination of experiments, combustion theory, and simulations. We determine combustion properties and pollutant formation trends, contribute to detailed and reduced chemical kinetic model development, and use computational fluid dynamics to study turbulence-chemistry interactions in combustion processes.

The ultimate goal is to develop tools for the analysis and design of advanced combustion devices such as gas turbines, internal combustion engines and industrial furnaces. We are also actively involved unravelling the physics of laser-induced initiation of burning processes; an approach that is promising as an alternative reliable ignition source for fuel-flexible engines. Other areas of research include thermodynamic analysis of energy systems and characterization of fuel blends.
