3D CFD simulation of a gaseous fuel injection in a hydrogen-fueled internal combustion engine

Nowadays, one of the hottest topic in the automotive engineering community is the reduction of fossil fuels. Hydrogen is an alternative energy source that is already providing clean, renewable, and efficient power being used in fuel cells. Despite being developed since a few decades, fuel cells are...
