摘要

摘要研究了限制水下空化射流的刚性圆柱框架与固体表面之间吸力的产生。在专门开发的装置中，通过实验测定了克服吸力效应所需的分离力。通过数值建模获得了吸力与框架直径和喷嘴空化器距离的关系。计算了框架内气相的体积分数和沿吸力面的静压。根据所获得的数据，解释了吸力效应出现的机理及其消失的标准。

Experimental and Numerical Investigation of the Cavitation-Induced Suction Effect

The generation of the suction force between a rigid cylindrical frame constricting a submerged cavitating jet and a solid surface is considered. The separation force needed to overcome the suction effect is experimentally determined in a specially developed setup. The dependences of the suction force on the frame diameter and the distance from the nozzle cavitator are obtained using numerical modeling. The volume fraction of the vapor phase inside the frame and the static pressure along the suction surface are calculated. The mechanism of the appearance of the effect and the criteria of its vanishing are explained on the basis of the data obtained.
