Abstract
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.
期刊介绍：
Fluid Dynamics is an international peer reviewed journal that publishes theoretical, computational, and experimental research on aeromechanics, hydrodynamics, plasma dynamics, underground hydrodynamics, and biomechanics of continuous media. Special attention is given to new trends developing at the leading edge of science, such as theory and application of multi-phase flows, chemically reactive flows, liquid and gas flows in electromagnetic fields, new hydrodynamical methods of increasing oil output, new approaches to the description of turbulent flows, etc.
