【摘要】 对一种顶部带有螺旋导流结构的新型旋流喷嘴的流场特性展开研究，通过实验的方式，对四喷嘴干涉喷淋的影响因素进行分析。四喷嘴干涉喷淋实验，分析入口压力、喷淋间距、喷淋高度对于干涉喷淋的影响。增大入口压力可以提高液滴的速度，但过大的入口压力会导致大量液滴积聚于中心位置；喷淋间距决定了有效喷淋区域的重叠范围，令干涉区域处于四个喷嘴的喷淋覆盖下；喷淋高度影响喷淋范围和液滴尺寸大小，喷淋高度过低时，液滴难以覆盖整个喷淋区域。更多还原

【Abstract】 The flow field characteristics of a new swirl nozzle with helical diversion structure at the top are studied. The influencing factors of four nozzles interference spray are analyzed through experiments. The influence of inlet pressure, spray spacing and spray height on interference spray was analyzed in four nozzle interference spray experiment. Increasing the inlet pressure can increase the droplet velocity, but excessive inlet pressure will cause a large number of droplets to accumulate in the central position. The spray spacing determines the overlapping range of the effective spray area, so that the interference area is covered by the spray of four nozzles. The spray height affects the spray range and droplet size. When the spray height is too low, it is difficult for the droplet to cover the whole spray area.更多还原
