Hydraulic shock that occurs in pipeline systems can cause accidents and destroy pipelines, valves and equipment. If the pressure fluctuates due to a hydraulic shock, the pressure in the rarefaction phase may drop below the pressure of saturated vapours, resulting in a cavitation. This phenomenon is accompanied by an additional increase in the amplitude of pressure fluctuation, which leads to additional loads occurring in the hydraulic system. The aim of the paper is to provide the method for calculation of the hydraulic shock with the help of OpenFOAM soft-ware complex, which considers the cavitation formation.
