摘要

重点研究了螺旋型和平面扇型喷嘴的喷雾和液滴特性。在灭火应用中一般采用螺旋喷嘴和平面扇喷嘴。在ANSYS中进行了计算分析。在不同的压力下，如1bar到3bar，测试了喷嘴参数，如喷雾模式，喷雾流量，冲击，韦伯数。在研究过程中，空气和水的体积分数保持相等。螺旋喷嘴的喷雾模式不均匀，喷雾产生的液滴粗糙。平扇喷嘴产生实心锥型喷雾，其影响区域为椭圆形，宽度约为其长度的1 / 2。与螺旋喷嘴相比，平扇喷嘴具有更高的喷雾流量和更大的喷雾冲击力。螺旋喷嘴具有最大的喷射角度和最小的液滴尺寸，因此被认为是高效的喷嘴。

Investigation of Spray and Droplet Characteristics of Spray Nozzles

The study was focused on investigating the spray and droplet characteristics of spiral and flat-fan nozzles computationally. The Spiral nozzle and the flat-fan nozzle are generally used in fire suppression application. The computational analysis had been carried out in ANSYS. The nozzle parameters like spray pattern, spray flow rate, impact, weber number were examined at different pressures say 1 bar to 3 bar. During this study the volume fraction of air and water were maintained equally. The spray pattern of spiral nozzle is not uniform and the droplets produced from the spray are coarse. The flat-fan nozzle produces a solid-cone pattern spray with oval impact area with a width of approximately ½ of its length. The flat-fan nozzle has higher spray flow rates and higher sprays impact than the spiral nozzles. The spiral nozzle acquires the maximum spray angle and the minimum droplet size and hence it is considered as highly efficient spray nozzle.
