The flow field at the outle of the pulse-jetting nozzle of a ceramic filter was measured using a hot-wire wind velocity indicator tbe jetted gas flow was obtained the influence of the jetting pressure and the pulse width on the jetted gas flow was analyzed .

采用热线 风速 仪测量陶瓷过滤器脉冲反吹喷嘴出口的流场得到了喷吹气体流量，分析了喷吹压力和脉冲宽度对喷吹气体流量的影响。
