%X 水力空化作为一种高级氧化技术，近年来在水处理领域得到了广泛的应用。特斯拉阀是一种被动式止回阀，反向导通产生空化。本文以特斯拉阀空化器为研究对象，空化体积为特征参数，研究了结构参数对空化效应的影响。结果表明，特斯拉阀中的空化现象主要发生在出口段；通过减小圆弧段半径和增大直流道倾斜角度，可以有效地增强空化效应；随着出口长度和直流道长度的增加，空化效应先增强后减弱且存在一个最佳参数。研究结果对研发新型水力空化消毒灭菌装置具有重要意义。<br />
Hydraulic cavitation as an advanced oxidation technology has been widely used in the field of water treatment in recent years. The Tesla valve is a passive check valve with a reverse guide to produce cavitation. In this paper, the influence of structural parameters on cavitation effect is studied by taking the cavitation volume as the characteristic parameter of the Tesla valve cavitation. The results show that the cavitation phenomenon of Tesla valve mainly occurs in the outlet section. The cavitation effect can be effectively enhanced by decreasing the radius of the arc section and increasing the inclination Angle of the DC channel. With the increase of outlet length and DC channel length, cavitation effect is first enhanced and then weakened, and there is an optimal parameter. The results are of great significance for the development of a new type of hydraulic cavitation disinfection and sterilization device.
