摘要:
齿盘剪切空化器内的流场及空化过程复杂,齿间的空化行为及空化特性研究一直是该领域的难点和重点。采用Zwart空化模型对齿盘剪切空化器内空化过程进行数值模拟。结果显示,动齿后缘局部区域的空化现象是离心力与机械剪切力的交替作用的结果。齿倾角对齿间空化效果的影响较大,且改变空化泡产生位置。齿盘剪切空化器内的空化在整个盘间呈多点分布,且分布均匀,空化强度高,累积空化体积大。高速旋转的齿盘间“点阵式”空化泡的产生具有连续、稳定特性,这对人们就齿盘剪切空化机理的探索、开发设计和应用具有重要意义。
Abstract:
The flow field and cavitation process in the shearing cavitation device with toothed discs is complex. Cavitation behavior and cavitation characteristics in the intertooth have always been the key problem in the field. The Zwart cavitation model is used to simulate the cavitation flow field in gear zone in a multi-layer rotor-stator gear shearing disc. It is concluded that the cavitation phenomenon in the local region of the trailing edge of the rotoring tooth is the result of the alternating action of the centrifugal force and the mechanical shearing force. The angle of tooth inclination has great influence on the cavitation effect between teeth and changes the position of cavitation bubble. The cavitation in the tooth disc shearing cavitator is distributed in multiple points, and the distribution is uniform, the cavitation intensity is high, and the cumulative cavitation volume fraction is large. The area occupation ratio of the corresponding cavitation bubble varies with a sinusoidal curve with the change of the rotation time of the shearing discs. The “dot matrix” cavitation bubble between the teeth of high speed rotation has the characteristics of continuity and stability. It is of great significance to the exploration, development, design and application of the shearing cavitation mechanism of toothed disks.
