Cavitation Demo Apparatus Manufacturer,Supplier and Exporter in India

Product Code : SCL-CELE-14129

The Cavitation Demonstration Apparatus is a compact bench top unit designed to visualize and study the cavitation phenomenon in water flow. Cavitation occurs when the local static pressure in a liquid flow drops below the liquid's vapor pressure, causing the release of vapor pockets (bubbles). This phenomenon is crucial to understand as the formation and subsequent collapse of these bubbles can lead to unsteady flow, reduced device performance (e.g., in pumps and turbines), and severe surface damage known as erosion pitting.

The apparatus uses a venturi shaped test section made of clear acrylic to allow for the visual observation of bubble formation and collapse. Cavitation is induced at the venturi throat by increasing the flow velocity, thereby reducing the pressure according to Bernoulli's equation. Flow control valves at both the upstream and downstream ends manage the flow rate, which is measured using a turbine flow meter. Static pressures at the upstream section and the throat are monitored using pressure gauges.
