I'd like to model a room, say 10x12x9, with R46 fiberglass insulation above the ceiling, R13 on 4 walls, and a heat source in the room to bring the room air temperature to 72F steady state. Everything around the room is an infinite well of sub freezing air. I want to measure the necessary energy input to the heat source. I'd also like to model PVC pipe manifold filled with a fluid, embedded in soil, the fluid pumped into a caste iron radiator located in the above room. Can you help me?

Can you please help me in calculating avg nusselt no. In a 3d channel? In which fluid is moving in turbulence and a constant flux is at base

[@engineeringtraining2024]

Yes

Thanks

Hello sir in my model I change some parameters value but it can changes accour only velocity profile not any changes in temp profile what are the problem?

[@engineeringtraining2024]

Hello, force or natural heat transfer?

[@azazullahkhan3188]

@@engineeringtraining2024 natural convection sir

Can i ask why heat flux comes from side walls ? Why did u choose wall 4

[@engineeringtraining2024]

It is dependent on your model and the boundaries conditions. You can use any boundary that you want.

can you help me to buid the heat transfer fluid flow

[@engineeringtraining2024]

Yes, sure
