Thesis Title

Combustion and auto-ignition of hydrogen/natural gas mixtures in reciprocating engines

Research overview

Exploring the combustion and auto-ignition behaviour of hydrogen/natural gas mixtures. Hydrogen has some very interesting contrasting combustion characteristics to NG including much higher flame speed, flame temperature, flammability limit and smaller quenching distance. Understanding how these parameters change the application of these blends to reciprocating engines will allow maximal decarbonisation of the energy sector. This is being undertaken with particular interest in boosted conditions to provide more applicable power generation. Additionally, the auto-ignition quantification method of gaseous fuels, the “methane number” has been shown to be inconsistent and unreliable and so alternative quantification methods are being explored.
