摘　　要：为提高机场除胶效率以及安全性能,基于空化理论,对除胶喷嘴进行设计改进。设计一种中心体剪切型复合空化喷嘴,并应用CFD软件对其在非淹没流场条件下进行分析及构型优化,并将优化后的喷嘴与锥形喷嘴、中心体喷嘴和角形喷嘴等几种典型空化喷嘴进行对比。研究结果表明,中心体剪切型复合空化喷嘴的空化效果及对冲击表面的冲蚀性能较原有的几种喷嘴有较大提升,其最佳结构尺寸为扩张角30°、嵌入深度3mm、出口段长度8mm、中心体直径3mm、最佳靶距15-25mm。When the aircraft takes off and lands,the tires would rub against the road surface to generate instantaneous high temperature.Under the action of heating and high-speed shearing,the rubber would form a build-up of rubber attached to the runway surface,which would affect the aircraft operation.Domestic airports generally removed the rubber regularly by high-pressure water.In order to improve the rubber removal efficiency and airport security,based on the cavitation theory,the design of the rubber removal nozzle was improved.A center body shearing compound cavitation nozzle was designed,and the CFD software was used to analyze and optimized it in a non-submerged flow field,and compared it with a conical nozzle,a center body nozzle and an angled nozzle.The research results show that the cavitation effect and the erosion performance of the impact surface of the center body shear composite cavitation nozzle are greatly improved compared with the original nozzle.The segment length is 8mm,the diameter of the center body is 3mm,and the optimal target distance is 15-25mm.
