Visualizing Flow Using IR Transparent Fluids

Click For Summary
SUMMARY

The discussion focuses on the challenge of visualizing flow using thermal infrared (IR) cameras, specifically addressing the limitations of water and the search for IR transparent fluids. Participants mention working with acetone and dichloromethane, which only provide transparency for a few millimeters. The goal is to identify fluids that maintain transparency for several centimeters. Carbon tetrachloride is noted as a fluid with no IR spectrum, making it a potential candidate for further exploration.

PREREQUISITES
  • Understanding of thermal infrared imaging technology
  • Knowledge of fluid properties and their interaction with IR light
  • Familiarity with chemical compounds such as acetone, dichloromethane, and carbon tetrachloride
  • Basic principles of fluid dynamics
NEXT STEPS
  • Research the properties of carbon tetrachloride for use in thermal IR applications
  • Investigate other potential IR transparent fluids suitable for flow visualization
  • Explore advancements in thermal infrared camera technology
  • Review scientific literature on the use of IR transparent fluids in flow visualization studies
USEFUL FOR

Researchers, engineers, and scientists involved in fluid dynamics, thermal imaging, and material science who are seeking to enhance flow visualization techniques using IR transparent fluids.

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.
