H2 has the potential to play a significant role in our global transition to carbon-free mobility. Manufacturers of internal combustion engines (ICEs) and gas turbines (GTs) are showing considerable interest in H2, with several OEMs already working on prototype engines that use H2 as a fuel. CFD is an effective tool for designing H2-powered ICEs and GTs, but H2 poses a number of modeling challenges: high injection velocities, low density, high mass diffusivity in air, wide flammability range, high burning velocities, and low ignition energy. In this webinar, we’ll discuss how CONVERGE CFD software is uniquely suited to address these challenges for various applications. We’ll look at examples including supersonic direct injection of H2 in ICEs, flame flashback control in dual-fuel ICEs and GTs, lean blow-off in GTs, accurate NOx modeling in ICEs, and the transition from deflagration to detonation in rotating detonation engines.
