Default FLUId-SoliD InteRACtion !!! any suggetion
Posts: n/a
I am undergraduate student .My final year project is due in 2 months. I need help

This project is related to some processing industry

My problem statement is:

In room there are pipes on groud for heating purpose. Hot gases are flowing inside these pipes and then convected to air in the room and then it should conducted through walls and then convected to ambient air.

I want to see the where the maximum heat lost is occuring.

I need to know how to model this in Fluent and or any CFD software

wat should be domain

Wat shuld be the boundary condtion at pipes , and walls

Thanks in advance

I would suggest you look at the Fluent documentation rather than posting the same question numerous times.

But I will provide a little head start....

If you intend to model everything, then you will have a conjugate heat transfer model with the hot gas and the wall thickness of the pipes. You then need to model the room as a natural convection (buoyant) domain (unless there is a fan driving the air in the room). Most likely it is sufficient to model the conduction through the room walls and apply a convection to the outside as a boundary condition. So you will have 2 FLUID domains (the gas in the pipe and the air in the room) and 2 SOLID domains (the pipe wall thickness and the room walls).

Good luck!
