Abstract

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
