I have modeled a testing furnace and I want to test a component at specific temperatures. Is it possible to perform a fluid-structure interaction simulation using OpenFOAM?
Mods please move to the CFD subforum, it’ll receive a constructive response there.
Ehsandehghani : Yes, a fluid-structure interaction is feasible in OpenFoam. If you look on the tutorials included in OpenFoam, you will please find a directory “heat transfer” with the following tutorials:
- buoyantBoussinesqPimpleFoam
- buoyantBoussinesqSimpleFoam
- buoyantPimpleFoam
- buoyantSimpleFoam
- chtMultiRegionFoam
- chtMultiRegionSimpleFoam
- chtMultiRegionTwoPhaseEulerFoam
- overBuoyantPimpleDyMFoam
- solidFoam
The solvers “buoyantSimpleFoam” (steady) and “buoyantPimpleFoam” (transient) are employed by CfdOf when you change the physics model to “compressible” and the checkbox “High Mach Number” remains unchecked. But I assume that input files for heat transfer without any modification cannot be generated from CfdOf because in CfdOf there are no thermal boundary conditions.
I have no experience with thermal simulations / heat transfer in OpenFoam, but there are a lot of tutorials on youtube which may help you.
Fluid-structure interaction (FSI) refers to fluid mechanics + solid mechanics analyses. What you describe is conjugate heat transfer (CHT). Btw. FSI is also possible using OpenFOAM but you need some solver for solid mechanics. CalculiX can be used for this purpose - it needs to be coupled with OpenFOAM using preCICE. That open-source tool also supports CHT with CalculiX if you need more control over heat transfer in a solid.
