Product Code : SCL-CELE-14011
This apparatus is a self-contained unit designed to visually
demonstrate and quantitatively measure the surface profile of a free vortex
(or potential vortex). This type of flow is characterized by the absence of an
external torque, where the fluid rotates due to the conservation of angular
momentum.
1. Key Components and Design
The setup is specifically configured to generate a rotation
without imparting significant torque.
- Vortex
Vessel (Cylinder): The fluid is contained in a transparent
cylinder.
- Material: Acrylic
(transparent for observation).
- Dimensions:
Diameter 200 mm (approx.), Height 200 mm (approx.).
- Vortex
Generation: Four circumferential jets are placed
along the circumference of the cylinder near its bottom.
- Function:
Water injected through these tangential jets causes the fluid to rotate.
Crucially, it is assumed that the torque exerted by these jets is
negligible once the flow stabilizes, forming a free vortex.
- Measurement
Probe: A pointer is provided.
- Function: This
pointer can be traversed horizontally and vertically across the
full diameter of the vessel.
- Purpose: To
precisely measure the shape and height of the hyperbolic water surface
profile formed by the free vortex.
2. Water Circulation and Flow Measurement
The system uses a rotameter for convenient, instantaneous
flow rate reading.
- Water
Circulation: Provided by an FHP Pump (Crompton make).
- Sump
Tank: Made of Stainless Steel (compatible capacity).
- Flow
Measurement: The flow rate is measured directly using a Rotameter.
- Control
Panel: Includes standard On/Off Switch and Mains Indicator.
3. Purpose and Experiments
The primary experiment is the verification of the theoretical
shape of a free vortex.
- Vortex
Profile Measurement: Measure the relationship between the radius r
and the water surface height z at various points.
- Theoretical
Verification: Compare the measured surface profile with the
theoretical equation for a free vortex, which predicts a hyperbolic
shape. The product of velocity and radius V cdot r is expected to be
constant (conservation of angular momentum).
- Visual
Observation: Observe the characteristic steep depression at
the center of the vortex.
