摘要：
In this paper, Malvern laser particle size analyzer is used to study the spray characteristic experiment of air atomizing nozzle designed by ourselves. We measured the MVD(medium volume droplet diameter) under different conditions. From the test result, the influences of air pressure, water pressure and ALR(air liquid rate) to MVD and uniformity are analyzed. Furthermore, the variation of the MVD from the distance increase is discussed. The three-dimensional flow field model is built to make numerical simulation by software FLUENT. The simulation results are very consistent with experiment results, which indicate the spray effect of atomizing nozzle is well, and the nozzle designed by ourselves can be well used for the spray system of ice wind tunnel.
