Product Code : SCL-CELE-14031
This equipment is a self-contained unit designed to visually
demonstrate and experimentally study cavitation, which is the formation
of vapor bubbles in a liquid when the local pressure drops below the fluid's
vapor pressure, typically occurring in high-velocity, low-pressure zones.
1. Key Components and Design
The apparatus is built around a transparent test section to
allow for visual observation of the cavitation bubbles.
- Test
Section: This is the core component where cavitation occurs.
- Material: Acrylic
(transparent), allowing for clear visual observation.
- Design: It
features convergent and divergent sections. The narrow throat of
the convergent-divergent section is the point where velocity is highest
and pressure is lowest, making it the primary site for cavitation.
- Pressure
Control:
- A control
valve is located at the upstream side to regulate the water
flow rate. Increasing the flow rate causes the pressure in the throat to
drop, inducing cavitation.
- Pressure
Tapings are provided at appropriate positions to monitor
pressure conditions.
- Instrumentation:
- Pressure
Gauge: Range 0–4 kg/cm² (to measure pressure
upstream/downstream).
- Vacuum
Gauge: Range 0–760 mmHg (to measure the low pressure
in the cavitation zone).
2. Water Circulation and Flow Measurement
The system uses a closed-loop circulation and a volumetric
method for accurate flow rate determination.
- Water
Circulation: Provided by a Pump (Crompton make).
- Sump
Tank: Capacity 60 liters.
- Flow
Measurement: Achieved volumetrically using a Measuring
Tank (Capacity: 40 liters) and an Electronic Stop Watch.
3. Purpose and Experiments
The primary goal is the observation and analysis of the
conditions necessary for cavitation.
- Cavitation
Demonstration: Visually observe the formation, movement, and
collapse of vapor bubbles as the flow rate is increased and the throat
pressure drops towards the vapor pressure of the water.
- Critical
Pressure Determination: Determine the flow conditions
(velocity and corresponding pressure) at which cavitation begins.
- Hydrodynamic
Study: Study the relationship between fluid velocity (measured
via flow rate) and the resulting pressure drop in the convergent-divergent
section, verifying the application of the Bernoulli principle to induce
low pressure.
