Fuel-film evaporation and combustion
The aim of this study was to develop optical diagnostics to investigate the impact of evaporating fuel films in combustion as a source of polyaromatic hydrocarbons (possible particle precursors) (PAH) and soot.
Higher wall temperatures increase the fuel-film evaporation rate.
High-speed color combustion-imaging visualizes the spray and fuel films, illuminated by a green LED, the flame front by chemiluminescence, and soot by natural incandescence.
High-speed combustion imaging reveals soot formation close to the evaporating fuel films
