Greetings

 

I'm working in Vapor Chamber problem (here is link to show how Vapor Chamber works)

 

To simplify the model, I have four layers stacking against each other (copper wall, wick with liqued water, vapor, copper wall). The boundary conditions and geometry is shown in the following PDF 

 

 

 

How much should the value of From Phase Frequency (s⁻¹) & To Phase Frequency for both mass transfer mechanisms (shown in the image below)?

 

 

 

It's worth mentioning that, I would like to have a balance in the model. I mean by that, there is enough liquid transfer to vapor for heat dissipation. And there is enough amount of vapor condensate and return to liquid phase

You only need one mass transfer as the evaporation-condensation works both ways. 

Coefficients are model dependent, and may need some tuning: that should be covered in the manuals, with potentially further information in the references and Knowledge base (Search tool on here).
