摘要：
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.
