MRT calculation in FLUENT

vaibhavraikhare · June 25, 2015, 05:52

Model Description: A room (10*10*10) in which chilled water is flowing at 14 degC into panels fitted on its ceiling. 6 heat source (100 W bulbs) were considered in the room. An air conditioner is fitted in the room to cater latent load of room.

My ultimately aim is to find Mean Radiant Temperature (MRT).

My Query is:
1. How can i make a black body in the room to find the globe temperature which helps to find MRT of room (you can find it https://en.wikipedia.org/wiki/Mean_radiant_temperature here).

If not then,
2. How can i calculate MRT (there is a macro defined in CFD post to calculate, but i am not able to understand).
