Hello,
I'm playing around with the new solver icoReactingMultiphaseInterFoam from OpenFOAM v1806, which is able to simulate evaporation with multiple phases. In the test case evaporationMultiComponent a massTransferModel is applied to have a phase change between water and gas. I'm wondering how to apply condensation in the same simulation to get a phase change from gas to liquid. Since the gas consist of 2 species (vapour and air) I'm wondering if condensation is possible with this setup. Below you can see the massTransferModel for the evaporation.





massTransferModel
(
(liquid to gas)
{
type kineticGasEvaporation;
species vapour.gas;
C 0.1;
alphaMin 0.0;
alphaMax 0.2;
Tactivate 373;
}
);

Hello Novel,
I started working with this solver as well, but unfortunately I have no idea about your question.


Btw, do you know whether diffusion of species from one phase to other is modeled in this solver?


Best regards,

Hi
I am currently working with icoReactingmultiphaseInterFoam solver in openfoam1806. I’m trying to use contact angle boundary condition for alpha_liquid or alpha_gas. But I’m not successful and always the result is the same by using different contact angles.
Has anybody been able to use this kind of boundary condition with this solver?
I’m wondering if there is a mistake in my way of enetering this boundary condition or this solver is not compatible with contact angle.
In this post, I have attached two baseCases. One case using interFoam solver with contact angle of 30 degree and another is using icoReactingMultiphaseInterFoam with contact angle of 30 degree. The results should be the same, but when you run it with openfoam 1806 or 1812, they won’t be.
I’m wondering if there is a mistake in my way of entering this boundary condition or this solver is not compatible with constantAlphaContactAngle boundary condition.
Thanks in advance

Hello Aliyah.,

I am using icoReactingMultiphaseInterFoam solver for simulate the flow boiling problem. I am facing the same problem in OpenFoam 1912. I could not able to simulate the flow boiling problem with contact angle in OF1912. contact angle is must required in my problem. I tried several times by adding constant contact angle value in alpha.liquid property but I didn't get any success. I did not find any change in the result with contact angle and without contact angle in icoReactingMultiphaseInterFoam solver.

Please help me if you have found a solution.

Thank You Very Much.

The negative value of C indicates condensation....
