Experimental circuit for the generation of cavitation in oil flow

The paper deals with the flow of oil through an experimental hydraulic circuit a convergent divergent nozzle circular cross-section. Under different physical conditions, i.e. changes in pressure, and temperature, formation development cavitation is monitored. As it highly dynamic transparent nozzle, monitored using high-speed camera frequency dissolution bubble movement cloud then determined. authors deal issue amount dissolved or undissolved air oil. Both variants influence formation, size area. This this case called cavitation. In technical practice, relevant, especially pump suction, where vacuum, leaks hence intake may occur.
