摘要
The impact of single droplets within a spray onto a thin liquid film produced by this spray has been studied using direct visualization and the phase Doppler technique. The temporal evolution of the crown radius and its height has been compared with results corresponding to the impact of an isolated drop onto an undisturbed liquid film. Significant differences in crown formation indicate to what extent interactions between neighboring drop impacts can affect the resulting secondary spray. The results of this study have significance for future modeling of spray impact. (C) 2002 American Institute of Physics.
