Hi Tim,

Thank you for your response, I did come to the same conclusion and have shifted to using the free surface models.

For these free surface models however, I have been unable to implement a cross flow of air to interact with the water jet being injected. I have been trying to use multiple lattices and coupling them with the air flow on one lattice and water flow on the other however I have not had any success.
Is coupling 2 lattices possible for the free surface models?

Thanks for your assistance,
Callum

Hi Tim,

I did see the convection type boundary condition, I will have a look into implementing this into my model.
Thanks for your assistance and best wishes for your current and future research.

Thanks,

Hi Tim,

Thanks for the response, I will be sure to check out the Peng-Robinson equation of state with Huron-Vidal mixing rules to get a better understanding of the parameters. I have managed to get it working without any boundary conditions, I had made a few mistakes when altering the geometry.
Regarding the outflow is there a different boundary condition that I should try using that can be more easily implemented?

Kind Regards,

Callum

Hi,

I have shifted to trying to make this model work using 2 lattices. The issue with implementing gravity is still something I have not had any success with so any help would be much appreciated.

Kind Regards,

Hi Tim,

Thanks for your help. Unfortunately I haven’t gotten around to trying to implement that yet.
I have been trying to define each fluid as a different density, i.e. fluid coming from inlet1 having a density close to air and fluid coming from inlet21 and inlet22 having a density close to water. I have so far had no success with this, does anyone have any suggestions on how I can implement this?

Thanks,
Callum
