Surface emissive power and virtual radiometers
 
Hi everyone!

I'm working on jet fires and I need to calculate the surface emissive power (SEP) using the P1 radiation model. Once the simultion is finished, I create an iso-surface with the molar fraction 5·10-4 of the fuel. However, I don't know how to get the results. Firstly I thought of using the Surface integral report, Flow rate, temperature, enthalpy, but I wasn't sure about it, then I used the Flux Report Radiation heat transfer option, but I the results weren't reliable...
Could someone help me please? Is there any option to plot the SEP?

One last thing, I've read somewhere the possibility of creating virtual radiometers, is it possible? how it must be done?

Thank you!
