Validation of a Reynolds-averaged numerical simulation environment to simulate high-pressure, auto-igniting hydrogen diffusion flames
N. Diepstraten, L. M. T. Somers, J. A. van Oijen
The hydrogen (H2) fueled direct-injection (DI) compression-ignition (CI) argon power cycle (APC) is an attractive technology to counteract the mismatch between energy demand and su…

A zero-dimensional global conservation model to determine non-ideal nozzle conditions for gas injections
N. Diepstraten, L. M. T. Somers, J. A. van Oijen
To reduce computation times of simulations involving gas fueled internal combustion engines (ICEs), a model is developed that determines non-ideal nozzle exit conditions to spare e…

FGM Modeling of Thermo-Diffusive Unstable Lean Premixed Hydrogen-Air Flames
Stijn N. J. Schepers, Jeroen A. van Oijen
Ultra-lean premixed hydrogen combustion is a possible solution to decarbonize industry, while limiting flame temperatures and thus nitrous oxide emissions. These lean hydrogen/air…
