Hi,

I am looking for help in calculating infrared (IR) signature for objects, especially in the mid-wave infrared (MWIR) and long-wave infrared (LWIR) regions. I realize ANSYS/Fluent can solve radiative heat transfer including solar irradiation.  However, I could find an option to calculate the IR signature from radiation intensities. Is there any option available in ANSYS/Fluent to calculate IR signatures? Are there any tutorials/examples available for these calculations?

Thank you in advance for your help.

The Ansys tools can help you model radiation emission, reflection & absorbtion. What are you actually trying to determine?

My goal is to calculate radiation contrast intensity (Watts per solid angle or W/Sr) at midwave infrared (3~8 micrometer) and longwave infrared (8~15 micrometer) range.  These "thermal images" are helpful for detecting objects using infrared sensors.  MWIR signature is important to detect higher temperature regions and LWIR is important to detect slightly lower temperatures regions.

Have a look at Speos.

I will. Thank you Rob.
