Spray-wall interaction: Diesel fuels impinging on a tempered wall
Journal article, 2006

Heat transfer from impinging sprays in direct injected diesel engines has been found to influence the rate of heat release and the formation of emissions. The use of multiple injections may also affect heat transfer. The objective of this work is to study heat transfer between the wall and the spray, and how the surface temperature of the wall affects spray behaviour in single and split injections. Two different diesel fuels were used in the experiments, noteworthy is that the diesel fuel had a higher radial penetration rate than the Idea fuel at evaporating conditions but not at non-evaporating conditions. The wall temperature has no measurable influence on radial penetration but does have a significant influence on the heat transfer.
