Description and Specification for Lab Tenders
Astra Scientific Cavitation
Demonstration.
DESCRIPTIONS:
The advanced self-contained apparatus to demonstrate and observe the basic principles of cavitation and its implications on the performance of hydraulic machines and systems.
This accessory consists of a circular Venturi-shaped test section manufactured from clear acrylic to enable visualization inside the section. As the flow of water increases the pressure at the throat falls in accordance with the Bernoulli equation until a limit is reached corresponding to the vapour pressure of the liquid. At this low pressure small bubbles of vapour form then collapse violently as the pressure raises again downstream – a process called cavitation.
Bourdon gauges indicate the pressure upstream of the contraction, inside the throat and downstream of the expansion in the test section. Flow control valves upstream and downstream of the test section enable the flow and pressure to be adjusted, enabling cavitation to be clearly demonstrated.
