For the majority of applications, air provides the most suitable testing medium. However, complex, three-dimensional flow fields are better understood through visualization.
Smoke traces generated in wind tunnels tend to be hard to control and dissipate rapidly downstream of the injection point. Visualization of the individual flow streamlines is not something easily undertaken.
A liquid can be used as the visualization medium, and water is the most common choice, because it allows a wide variety of visualization techniques to be employed. These can range from something as simple as food coloring injected into the flow to
We have been designing and manufacturing water tunnels since 1986, and key features include:
Shear layer tunnels, systems for studying aquatic wildlife, and applications that require different mediums can all be easily accommodated with slight modifications to the standard designs.
