Lean Premixed Prevaporised Combustion for Microturbines
… strategy to meet these requirements is the lean premixed prevaporised (LPP) concept. Thus, this thesis explores the fuel flexibility, flame stability, structures, gas emissions, and droplet behaviour in LPP combustion at conditions relevant for microturbines. The first part of the thesis …

Simulating Extinction and Blow-off in Kerosene Swirl Spray Flames
… stability phenomena like flame extinction and lean blow-off (LBO) are still not well-understood for conventional spray flames, but alternative fuels provide additional challenges as they have been observed to have increased variability from expected behaviour at conditions close to LBO. …

Experimental investigation of unconfined bluff body stabilised flames with vapourised kerosene fuels
… technologies have increasingly implemented lean premixed flames as they facilitate low NOx and soot emissions. In most modern transport vehicles, combustion occurs under highly turbulent conditions. However, stabilizing lean premixed flames within the high Reynolds number conditions of …

Transient Phenomena in Annular Combustors
… gas turbine combustors, namely ignition and blow-off. The experiments were conducted on complex multi-burner geometries, close to realistic combustors, to provide a wide data set including stability limits, flame regimes and physical mechanisms of ignition and extinction. The first part of …
