Aidan recently graduated from the University of Wales Trinity St David with a BEng in Motorcycle Engineering. Prior to his studies, he gained five years of hands-on experience as a motorcycle mechanic, specializing in Ducati motorcycles. During his degree, Aidan discovered a passion for combustion, culminating in his final year project, which focused on combustion and emission modelling for a GDI engine using MATLAB. In his free time, Aidan enjoys restoring motorcycles and is currently rebuilding a Yamaha WR250.
Hydrogen is a carbon free fuel that has the potential to reach zero emissions in an Internal Combustion Engine (ICE). Long range and fast refuelling are significant requirements for a modern propulsion solution for the automotive industry. At a lower cost than fuel cell electric and battery electric vehicles, Hydrogen ICEs rely on a mature industry with the potential for rapid deployment for fast emissions reduction.
Hydrogen's wide range of operational limits allow for extremely diluted combustion, which can significantly reduce combustion temperatures and therefore notable nitric oxide (NOx) emissions. However, this diluted burning can trigger flame instabilities that complicate modelling efforts that contribute to engine development.
Experimental data will be gathered from a hydrogen engine, to explore operating points and configurations that have yet to be evaluated. Modelling of the combustion and emissions from this hydrogen engine will be undertaken using 3D Computational Fluid Dynamics (CFD) to analyse combustion and emissions mechanisms.
Through this analysis, the project aims to enhance understanding of hydrogen combustion and emission formation mechanisms to optimise hydrogen engine development.
