摘要
针对密闭容器内喷雾场PDA测量中一些关键问题 ,如实验光路调整、非正交光轴的正交化处理、测量窗的选择及其清洁、由于水滴直接打在测量窗口等原因引起水膜振动对测量结果的影响、PDA的测量数据可重复性和时效性进行了分析研究 。
Some key problems encountered in the spray field measurement in a close- container with PDA system, such as the calibration of PDA laser sets, non-orthodox laser axis transform, the selection of measurement windows and their cleanness, the impact of vibration of water film on measurement result owing to some big droplets beating the window, the data repetition and valid time characteristic of PDA system, are analyzed in this paper in detail. The conclusion and some useful advice are available to guide the PDA measurement.
