Samuel J. Kazmouz

Research Engineer


Dr. Samuel J. Kazmouz is a Research Engineer in the Transportation and Power Systems Division at Argonne National Laboratory. As part of the Fuel Cell and Hydrogen research group, Dr. Kazmouz models Liquid Alkaline Water Electrolysis (LAWE) systems for Hydrogen production.

Previously as part of the Multi-Physics Computational research group, Dr. Kazmouz utilized numerical methods to study reacting flows in energy and propulsion systems for the purpose of decarbonization:

  • Developed predictive ignition modeling capabilities to aid industry in designing high-efficiency and low-emission power and propulsion systems.
  • Investigated hydrogen substitution in large-bore rail engines towards carbon-zero locomotives.
  • Explored multi-device acceleration of physics-based models for hybrid-architecture supercomputers. 

Prior to joining Argonne:

  • Investigated cyclic variability in a stratified-charge direct-injection spark-ignition (DISI) engine by using high-fidelity multi-dimensional large-eddy simulations.
  • Extended a turbulent flame model (thickened flame model) to account for non-premixed flames in engines.
  • Developed a shale gas model for gaseous flow in tight porous media.
