Methods for changing rate of radiative heat transfer
Methods for changing rate of radiative heat transfer
(OP)
Hello,
I'm working on a project where I have an 3' x 4' object that's temperature ranges between 300 and 400 C. I cannot contact the object but need to regulate the radiative heat flux. I have a water cooler chiller and and thinking of modulating the flow of the chiller water to vary the temperature of a heating/cooling plate. If the temperature of the plate increases to 40 C, I have one rate of heat flux. If it increases to 99 C, I'll have another.
I'm not a thermal engineer by any stretch of the imagination and wanted to get advise on whether this approach would work or solicit feedback on other approaches.
I'm also interested in understanding if there are any liquids that I could use to get the plate temperature to 200 C as this is another consideration but not a requirement.
Regards,
HD

I can do the engineering.. I just wanted to ensure the concept was sound. What are the high temperature fluid considerations. Are there any watch outs for stabilizing the cold plate temperature.

If so, then you would know the difference between controlling the radiation vs. controlling the temperature. What is the requirement? If you have a cooling plate, then what's the issue; isn't it simply a closed-loop thermal control?

IRstuff.. I am controlling the radiation by controlling them temperature of the cold plate. The requirement is to vary the heat flux and reduce flux variation.
