Hello Guys
I am modeling the case of natural ventilation in a single heated space. I have drawn a plastic room and drawn around it the fluid which i water. Then I subtracted them from each other preserving the room. I have then drawn a small solid inside the room and subtracted it from the fluid without preserving it. Then I defined that face as a heat source while defining the other faces of the fluid as inlet, outflow, and walls. I have attached the picture of the model. My problem is in the results I get. They are weird because the heat source is only heating the water below it without heating those above it. Please advise Untitled.jpg |

Have you considered having the inner box as source rather than just the lower wall?

I have tried to do this but had the same results. Previously I didn't get rid of the box but instead kept it and defined it as a heat source but I had the same results.

Why are you using shell conduction? I mean what is the purpose?

The intention was to duplicate an experiment that was done at our lab and we had stuck to all the data and materials used. Nevertheless, I have solved my problem by deleting both the heat source and the plastic room and only kept the water. Thanks anyway and hope I didn't bother you.
