Flow in a duct
I have a triangular duct ....
In that i have a fin..........
now I want that the fin should conduct heat from outer wall to fluid flowing through the duct...
so i have two volumes...........one is of duct and other is of fin.
should i use the retain option while subtracting fin from the duct volume.
as when i simply subtract.... the heat transfer reduces..... because there becomes a hole in the bottom wall which is at 400 k
I will mail the files, if any one, can give suggestions on how to do it....
I have no experience with solid conduction, but if you want to compute it, you need the 2 volumes.
So the retain option should be choosen.
Define the fluil domain as fluid and the fin volume as solid
Dear Max, Its a Convection Problem
When I retain the volume and put it as solid in continuum , then I get a floating point error in fluent.
I wish to send the files to you
if you don t need solid conduction, then don't retain the fin volume.
You will have a hole in place of the fin.
Then just set the termal conditions for the fin's walls.
I am Sorry , You were right.
Its a Conduction + Convection Problem.
now I will try with retain option...
I am sure.....this time...some thing will come out....
I was a lot confused in this matter.....and you solved it Instantaneously...
Hats off to you........................
You are my Hero.......
I have made two volumes now...
Now I split volumes instead of subtract.....
I think that option will work ....
Max could you possibly check... whether I am doing correctly or not
it depends on your both geometries.
If first geometry is already the fluid domain, and the second the solid domain, then you don't need to do anything (perhaps disconnecting both volumes because of solid conduction, but as I sais I am not experienced in this area).
Did you already solved convection (only fluid domain)?
