interRegionHeatTransferModel
 

I am trying to create a heat transfer model using chtMultiRegionFoam. In this model I am trying to simulate a heater using a constant internal heating term. I looked into how other people have attempted to do this in OF1.7 but I think these threads are outdated as there has been considerable change to the solver.

I am only working with solid components so the solver for this section looks like:

fvm::ddt(betav*rho, h)
- fvm::laplacian(betav*alpha, h, "laplacian(alpha,h)")
==
fvOptions(rho, h)

I looked into adding a source term to the above equation, but it seems as though fvOptions has the capacity to act as heat source term using interRegionHeatTransferModel. Since this is a relatively new feature I cannot find any documentation or examples of how to implement this. I already looked at OF2.2 tutorials with fvOptions and turned up empty.

Has anyone here used, or has an example/tutorial of how to implement fvOptions::interRegionHeatTransferModel as a constant heat generation source.

I'm facing the same problem.

Does someone have an example of interRegionHeatTransferModel as a constant heat generation source?

Thank you,

Dear openFoamers,

This topic still for me unsolved.

How to add heat source to a given region?

Any idea?

Hi Peter,

You can add a heat source using fvOptions with the "scalarSemiImplicitSource". This is quite straightforward and you can use different selectionMode depending on what you want to do. (ie: using a cellZone to add a heat source in a specific volume inside your domain)
