fanPressureJump BC with buoyantPimpleFoam

Hi all,
I'm currently working on a project to simulate heat transfer through air in a confined space between a heating element and an evaporator and I am having trouble implementing the fanPressureJump BC. So far I have been able to setup my mesh and now I am working on adding the fanPressureJump BC to represent the evaporator blower. I have followed the TJunctionFan tutorial and I was able to modify the tutorial by adding my own custom mesh and I get reasonable results when running pimpleFoam. The issue I am having is that when I try to switch the solver to buoyantPimpleFoam in order to incorporate buoyancy effects the fanPressureJump BC seems to cease functioning. I used the hotRoom tutorial as a starting point for the constants, fvSolution, fvSchemes, and controlDict files. I have attached images of the U magnitude results after 0.3 s from pimpleFoam and buoyantPimpleFoam and I have also attached a zipped file of the case. Any help is much appreciated. |

I was able to resolve this issue by applying the fanPressureJump BC on the p_rgh file instead of the p file.

hello,I encounter this problem as well,do you mean applying fanPressureJump BC on the system/createBafflesDict as well as the 0/p_rgh file?
Thank you in advance! |

I appreciate your feedback as it saved me.
I've been struggling with a cyclic patch for the fan to work in buoyantSimpleFoam. after applying topoSet and createBaffle to produce the patch, the solver automatically assigns the pressure jump to "p" and not "p_rgh". I copied the cyclic patch from p to p_rgh and now is functioning. p_rgh ---------- cyclicFaces_master { type fan; patchType cyclic; jump uniform 0; value uniform 0; jumpTable constant 15; } cyclicFaces_slave { type fan; patchType cyclic; value uniform 0; } |
