摘要

采用局部时移方法，结合SpraySpy装置和高速可视化技术，对单组分流体（水）在单纯形雾化器中的分散进行了详细研究。液滴的平均大小和速度分布取决于雾化器的压降。两种不混溶的液体（煤油和水）喷射到同一个雾化器是通过影子摄影可视化。结果表明，双组分乳化液在靠近雾化器出口孔处几乎瞬间崩解，导致喷雾锥明显变形。

EXPERIMENTAL STUDY OF A TWO-COMPONENT EMULSION PRODUCED BY A SIMPLEX ATOMIZER

The dispersion of a single-component fluid (water) by a model simplex atomizer is studied in detail using the local time-shift method with a SpraySpy device and high-speed visualization. The mean size and velocity distributions of droplets are measured depending on the pressure drop for the atomizer. The spraying of two immiscible fluids (kerosene and water) supplied to the same atomizer is visualized by shadow photography. It was found that the two-component emulsion disintegrated almost instantaneously in close proximity to the atomizer outlet orifice, resulting in significant deformation of the spray cone.
