Cavitation Demonstration
Item Code: RF 017
Cavitation refers to the formation of vapor bubbles in flowing fluids due to strong low pressure. As the flow velocity increases, the static pressure of the fluid falls to the vapor pressure and leads to the formation of vapor bubbles. The bubbles are carried along by the flow and implode if, with decreasing velocity, the static pressure rises above the vapor pressure of the fluid. To visualize the flow processes the experimental unit includes a Venturi nozzle made of plexiglass. There are 2 pressure measuring points on the Venturi nozzle: at the inlet and at the narrowest point. The flow rate and the pressures can be adjusted via two ball valves. In this unit cavitation phenomenon can be observed when small bubbles begin to appear.
