Abstract
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.
Highlights
The emergence and development of cavitation in the industrial equipment and the transportation routes significantly affects the reliability of their work and operating conditions
The issues of identifying the beginning of cavitation and critical parameters of fluid flow depending on the geometry of the object, the type of fluid and flow parameters have great practical importance
The total gas content of the liquid is determined by the amount of dissolved and free gas
Summary
The emergence and development of cavitation in the industrial equipment and the transportation routes significantly affects the reliability of their work and operating conditions. The research of cavitation processes is a difficult task. It is common to associate the discontinuity of a fluid with the presence of so-called cavitation embryos in a liquid (any inhomogeneities in the liquid).
