Spray-methane flame photographs with methane flow rate increasing from left to right.
Flames with two fuels, like the spray-methane flames we study, provide a challenging target for combustion and chemical model validation and have relevance for spray piloted natural gas engines and fuel switching gas turbines. I'm interested in studying the stabilisation characteristics of flames in which two fuels burn with a shared oxidiser. This involves a spray in an oxidiser of premixed methane and air. This work involves flame imaging and statistical analysis of flame structure, stabilisation, ignition, and extinction phemomena.
