摘要：
The gas entrainment into a non-vaporizing single-hole Diesel spray submitted to variable density is studied experimentally in order to better understand the effect on mixture formation. Particle Image Velocimetry on fluorescent tracers has been applied to obtain measurement in the flow field surrounding the spray. The "quasi-steady'' region of the spray (far from the head vortex) as well as the non-stationary region has been investigated. Significant effects of both ambient density and nozzle diameter on gas entrainment have been pointed out.
