摘要
以自激振动空化射流喷嘴为研究对象,以其在工业清洗中的应用为研究背景,通过设计具有不同结构参数的喷嘴,着重探讨了谐振腔长与出口孔长之比,谐振腔长径比等结构参数对射流特性的影响规律,并通过打击力和清洗力实验来对喷嘴射流特性进行评价.实验表明:谐振腔长与出口孔长之比在0.2～0.3区间时的打击力较高、清洗效果最好;同时还得出在操作压力一定的情况下,当谐振腔长径比为0.33时测得的打击力最大.
In order to determine the optimum parameters of structure of the self-resonating cavitating jet nozzle so that it can he used in the industrial cleaning more efficient,two parameters of the nozzle were considered：one was the length ratio of resonator and outlet hole ,the other was the length to diameter ratio of the resonator. The impact force and cleaning ability were selected as the criterion to evaluate the property of the jet. Results show that when the length ratio of resonator and outlet hole is between 0.2 and 0.3 ,the impact force and cleaning ability, reach the highest value. If the operate pressure is constant,then the impact force will get its the highest value at the point which the length to diameter ratio of the resonator was 0.33.
