摘　　要：通过测定陶瓷过滤器引射器喉管处的瞬态流场得到了脉冲反吹过程中引射气体流量随时间的变化规律 ,分析了喷吹压力和脉冲宽度对引射气体流量的影响。依据喷吹气体流量的实验结果 ,得到了不同喷吹距离时的动态引射比随时间的变化规律。结果表明 ,喷吹距离是影响引射性能的一个重要参数。The change law of the injected gas flow varying with time in the back pulse jetting process was derived by measuring the instantaneous flow field at the throat of the injector in a ceramic filter, the influences of the jetting pressure and the pulse width on the injected gas flow were analyzed. The change law of the instantaneous entrainment ratio varying with time at various injecting distance was derived based on the experimental result of the injected gas flow. The result shows that the injecting distance was an important parameter for the injecting performance.
