Cavitation refers to the formation of vapour bubbles in flowing fluids due to strong low
pressure. As the flow velocity increases, the static pressure of the fluid falls to the vapour
pressure and leads to the formation of vapour bubbles. The bubbles are carried along by the
flow and implode if, with decreasing velocity, the static pressure rises above the vapour
pressure of the fluid. SMT-FM-29 is suitable for the demonstration of cavitation processes
using the example of a Venturi nozzle. Pressure energy is converted into kinetic energy and
vice versa in the Venturi nozzle. Vapour bubbles form in the narrowest cross-section. To
visualise the flow processes the experimental unit includes a Venturi nozzle made of
transparent plastic. There are three pressure measuring points on the Venturi nozzle: at the
inlet, at the narrowest point and at the outlet. The input pressure can be adjusted via a
pressure reducing valve. The flow rate and the pressures can be adjusted via two ball valves
which are located at the inlet and outlet of the pipe system.
