Experimental methods are the most obvious and reliable in cavitation studies. The number of bubbles of insoluble oxygen in a flow influences cavitation hrocesses. In order to reduce the amount of dissolved gases in the experimental setup, it is proposed to use a resorber. The flow regimes of fluid flow around a solid with the formation of a cavitation zone in the flow are investigated. The type of cavitation flow is determined. A comparison is made of the experimental results of the formation of cavitation conditions before and after the installation of the resorber. The experiments were carried out with technical tap water, the reliability of the results is confirmed by comparing them with the literature data

The article describes the approach to determining the flow regime using the experimental hydrodynamic stand for researching the cavitation processes. A series of experiments with technical tap water was performed, which allowed to confirm the reliability of the results obtained by comparing them with theoretical values. The researched values include mean flow rate, Reynolds number and cavitation numbers. Conclusions about the type of cavitation flow was made.

Mathematical modeling of the liquids movement, accompanied by the phenomenon of cavitation, is developing intensively, but the super-cavitational flow regime has a number of features compared to the localization of the cavity on the streamlined body. The article presents a general approach to the mathematical modeling of the supercavitational flow, describes the used mathematical model. The geometry selected for modeling, the initial parameters and the physical constants characterizing the process are given. Using ANSYS CFX, the flow around a cone installed in a round tube at different flow velocities was calculated. The analysis of the obtained results was carried out, and directions for further research were outlined.

An experimental installation for studying developed cavity flows is described, including a separator for removing free air and gases from the stream, and a device for determining the flow rate. Experiments of flow around the restriction in the form of flattened cone were carried out. The dependences of cavern sizes and pressure on the working section from the free-steam flow velocity are obtained.
