Species Mass Transfer, Multiphase setup problems..?
I am trying to simulate multiphase flow. Specifically, my inlet is carbonated water, and my geometry is venturi (converging diverging nozzle shape). So, through nozzle, the pressure will change, and solubility will be also changed. So, I want to see the CO2 in carbonated water is undissolved from carbonated water, and escape to ambient air.
I am trying to use multiphase Eulerian, species transport model, mass transfer from species to species with Henry's Law.
I am setting up...
- mixture: CO2 and water
- mixture: CO2 and air
- mass transfer
- mixture (CO2 and water): CO2 --> mixture (co2 and air): co2
- in order to represent undissolved co2 from carbonated water
Is this right setup to represent this phenomenon?
I keep getting divergence in residual...it says it is detecting floating point....
Could anyone give me some advice?
