Structure of Unsteady Sprays Injected from Pintle-Type Nozzles,
Abstract
The temporal and spatial characteristics of the transient diesel spray injected from a pintle-type nozzle into the atmosphere were investigated by phase Doppler anemometry and its structure visualised by high speed photography. The droplet velocities and sizes were quantified near the nozzle exit and the degree of fuel atomisation deduced from the fractal dimension estimated from the droplets size distribution. High frequency periodic structures were identified on the surface of the transient spray and attributed to aerodynamic interactions between the injected fuel and surrounding air. (Author)
