Product Code : SCL-CELE-14005
This apparatus is a self-contained unit specifically designed
to demonstrate and study the phenomenon of cavitation in water flow.
Cavitation occurs when the static pressure of the fluid falls below the fluid's
vapor pressure, leading to the rapid formation and subsequent collapse of vapor
bubbles.
Key Components and Design
The setup is built around a transparent test section to allow
for visualization of the cavitation process.
- Test
Section: Made of Acrylic (transparent material).
- It
features convergent and divergent sections. The narrowest point
(throat) in the convergent-divergent section is where the flow velocity
is highest and the pressure is lowest—the critical location for inducing
cavitation.
- Pressure
tapings are provided at appropriate positions to monitor the
pressure before and after the throat.
- Pressure
Measurement:
- Two
Pressure Gauges are connected to the tapings for pressure
readouts.
- Pressure
Gauge Range: 0 to 4 $\text{kg/cm}^2$.
- Vacuum
Gauge Range: 0 to 760 mmHg (millimetres of mercury).
- Flow
Control: A control valve is fitted at the upstream
side of the test section to regulate the water flow rate, which is
necessary to achieve the low pressures required for cavitation.
Water Circulation and Flow Measurement
The system uses a large-capacity closed-loop system for
circulation and a volumetric method for flow rate determination.
- Water
Circulation: Provided by a Pump (Crompton make).
- Sump
Tank: 60 Liters capacity.
- Flow
Rate Measurement: Achieved using a Measuring Tank (40
Liters capacity) and an Electronic Stop Watch to calculate the
volumetric flow rate.
Purpose and Experiments
The primary experiment involves reducing the static pressure
at the throat of the test section until it reaches the vapor pressure of water,
at which point cavitation bubbles form.
- Cavitation
Demonstration: Visually observe the formation and collapse of
vapor bubbles (cavitation) in the acrylic test section.
- Pressure
Study: Measure the pressure readings (including vacuum) at the
critical points to correlate flow conditions with the onset of cavitation.
