Visualizing Flow Using IR Transparent Fluids

In summary, the conversation is about the search for room temperature IR transparent fluids. The speaker mentions their work with thermal infrared cameras and explains that water is not transparent for IR light. They are currently looking for liquids that are transparent for a greater distance, and are asking for suggestions or research/articles on the topic.

Hi.
I am working on visualization of flow with thermal infrared camera. As it is known, water is not transparent for IR spectrum of light, so you can`t watch phenomena that are occurring "inside". You can only see things that are occurring on the interface of water and wall.

I have been working with some fluids like acetone or dichloromethane, which are transparent only few millimeters.
Now I am trying to find liquids that are transparent more than that, let`s say few cm.
So, has anybody been working with such a fluid or does anybody know for a research/article, which has dealed with this things?

Thx.

Hi,

I am also looking for room temperature IR transparent fluids. Were you able to narrow down any fluids with such property ? Please suggest.

Thank you !

Carbon tetrachloride has no IR spectrum.
 

What is "Visualizing Flow Using IR Transparent Fluids"?

"Visualizing Flow Using IR Transparent Fluids" is a scientific technique that involves using fluids that are transparent to infrared light to visualize the flow patterns of liquids or gases in a system. This technique is often used in fluid mechanics and aerodynamics research.

How does "Visualizing Flow Using IR Transparent Fluids" work?

In this technique, an IR-transparent fluid is injected into a system or flow field, and then infrared light is shone through the fluid. The fluid will absorb the infrared light differently depending on its velocity and flow direction, allowing researchers to visualize the flow patterns in the system.

What are the benefits of using IR transparent fluids for flow visualization?

Using IR transparent fluids allows researchers to obtain a more accurate and detailed visualization of flow patterns than traditional methods using dyes or particles. It also allows for non-intrusive and non-invasive measurements, making it ideal for studying complex and sensitive systems.

What are some common applications of "Visualizing Flow Using IR Transparent Fluids"?

This technique is commonly used in various fields such as aerodynamics, fluid mechanics, and biomedical engineering. It can be used to study the flow patterns in wind tunnels, internal combustion engines, blood flow in the human body, and more.

What are some challenges or limitations of using IR transparent fluids for flow visualization?

One of the main challenges is finding an IR-transparent fluid that matches the properties of the fluid being studied. Another limitation is that this technique is sensitive to changes in temperature and pressure, which can affect the refractive index of the fluid and distort the visualization. Additionally, the equipment and expertise required for this technique can be expensive and specialized.
