FixedValue of Temperature for a volume
Hello,
Problematic : Is it possible, with OpenFOAM, to define a fixed temperature for a volume (named cellzone) ? Explication : My problem is that i have a box in a room. I define the temperature field in my box as : Code:
dimensions [ 0 0 0 1 0 0 0 ]; But after 1 iteration, the fluid cool the box (293 vs 353), so the temperature of my box go down. How can i fix the value in my box ? (I can't delete my interface ?!) Thank you for any hint Best regards. m_f |
Hi,
if you want temperature in your box fixed, then you do not need to model it! Simply, model box2 and fluid and where the box is, use a Code:
type fixedValue; could you add a picture of your problem thus everything is clearer? mad |

Finally my goal is to calculate the heat transfert throw box1 faces, with wallHeatFlux (even if i don't know nowadays how it's work....:confused:). I use topoSet and splitMeshRegion to create my boxes and my fluid meshes. splitMeshRegion creates automatically my bondary as : Code:
For interface between region fluid and box2 added patches Or I have to modify an existing patch, to put fixed value ? I'm a bit lost :/ Quote:

I have never used wallHeatFux (even though I tried to...). However, calculating the heat transfer should not be a problem...
As for the case: you can delete the box mesh. Interfaces box_to_x can be defined as patch and you can use whenever bc you want on it. mad |

For information, bondaries of box1 are defined as : Code:

your fluid has "external" domains, right? your box1_to_x patch must be defined as that one. look at the boundary file and copy the definition (not the nFace startFace though!)

No, it's a internal fluid, in a kind of canalization. Sorry, i wasn't clear, there are walls all around the fluid, barring inlet and outlet.
But...It's work ! As you said, I modified some point : All box1_to* or *to_box1 were modify : Before : Code:
box1_to_box2 Code:
box1_to_box2 But, destroying the compressible::turbulentTemperatureRadCoupledMixed wall conditin to a fixedValue, Is the radiation effect of my box1 in the fluid destroy ? I don't really understand how Qr file is used... Code:
Extract of /0/fluid/Qr : m_f |
