LT-FU116 Visualization of Streamlines in an Open Channel

Device Image
Description Technical Details

The Labtronic Visualization apparatus is designed for studying fluid dynamics in open channels. It features a transparent tank and flow channel that enable easy visualization of flow patterns around drag bodies, weirs, and vortices. With the ability to experiment with two different weirs and four drag bodies, this apparatus is highly versatile.

The streamlined channel entry is fed with water from a transparent tank containing marbles to reduce turbulence and ensure smooth flow. The flow rate through the channel can be easily controlled using the control valve. The water discharging from the channel is collected in the volumetric tank of the Hydraulics Bench and returned to the storage water tank.

To further enhance the visualization of flow, a dye injection system has been incorporated at the inlet to the channel. This system consists of a reservoir, flow control valve, manifold, and hypodermic tubes. By using a graticule on the rear face of the channel, the flow can be easily visualized and analyzed. Overall, the Labtronic Visualization apparatus is an ideal tool for studying fluid dynamics in open channels, offering both versatility and ease of use.

Learning Objectives:

Visualizing flow patterns around weirs and other objects in an open channel, and study the characteristics of flow in an open channel.

  1. Demonstrating the basic principles of the open channel flow.
  2. Visualization of flow patterns over or around immersed objects of different shape and size.
  3. Demonstrating the relation between different shapes and flow.
  4. Visualizing streamlines flow through drag bodies and weirs.
