摘　　要：对舱壁喷头的流量特性进行试验测试,将试验结果与理论计算进行对比。结果表明,喷头的流量与压力成正比;缝隙宽度对喷头喷淋角度有较大影响,在缝隙宽度较小时,由于摩擦等原因,舱壁喷头的喷淋角度小于其实际开口角度,导致喷头的实际流量与理论计算存在一定差距。在类似喷头设计时应保证缝隙宽度,通过调整缝隙长度来实现流量的调节。The flow characteristic of sector nozzle was experimented and the results were compared with theoretical calculations.The results showed that the flow of the nozzle is directly proportional to the pressure.The width of gap has a great influence on the spray angle.When the nozzle gap width is small,due to friction and other reasons,the spray angle is smaller than the actual opening angle,resulting in a certain gap between the actual flow and the theoretical calculation of the nozzle.In the design of similar nozzle,the gap width of should be ensured and the flow rate can be adjusted by regulating the gap length.
