摘　　要：喷嘴雾化在能源动力、化工、农业和环境工程中有非常广泛的应用,研究喷嘴雾化的流动特性是两相流研究中一个重要课题。对粒度分布等雾化特性的研究,有助于对喷嘴雾化机理的了解以及雾化结构的优化。本文简要介绍了PDPA基本原理和研究状况,综述了应用PDPA测量喷嘴雾化特性的实验研究进展,并提出了对此研究的展望。Nozzle Spray is very popular in power, chemical, agricultural, and environmental engineering,and it is an important part of the research on two-Phase flow. The investigations of the spray characters suchas the droplets diameter distribution is helpful to understand the principle of spraying and optimize the sprayconfiguration. In this paper, the basic principle and the research status of PDPA are briefly described, theexperimental studies on the measurements of the spray characteristics by applying PDPA measurement systemsare reviewed, and the prospects for this research is presented.
