Authors Abstract
Content
The objective of this research is to investigate the behavior of interacting sprays, so-called spray clusters, under typical Diesel combustion conditions. Visualizations and Phase-Doppler Anemometry are employed to characterize the macro- and microscopic spray properties. A significant effect of the cluster geometry on spray formation is noticed. Direct spray-spray interaction is found in all cases, with varying intensity depending on the included angle of the orifices within a cluster. The sprays from all investigated cluster nozzles penetrated significantly slower than those of a comparable conventional nozzle. The stability of the sprays is found to be very sensitive to the orientation of the cluster. Depending on this parameter the sprays from one cluster penetrate very similar or exhibit significant instabilities, especially at lower injection pressures.
