Surface tension
I am simulating flow through capillary section and interested on observing the movement of liquid - gas interface. When I set the Surface Tension Force to Continuum Surface Force, the interface is moving very slow and liquid surface diffusing into the gas medium. And when I set the Surface Tension Force to None, I am observing fairly good interface movement without diffusion. I will appreciate your comments and suggestions on this.

Hi,
CFX is hopeless at surface tension modelling. I have done extensive testing of CFX in this area in the last few months and have found Fluent to be far better - both much faster and more accurate. I strongly recommend you change software. Glenn Horrocks |
Re: Surface tension
Hi Glenn,
Thank you for your answer and recommendation. I guess, I can have a chance to test the problem with the fluent as well. |
