Hi
I work on a two phase flow in a channel (2D axisymertrique), The gas is injected through a nozzle which has a thickness (internal Ryon = 0.1 mm and external Ryon = 0.2 mm), using interFoam The triple contact line moves over time. It moves between the inner diameter and the outer diameter of the nozzle. I want to know if this is a miscalculation, or I have to fix the triple line or contact angle at the nozzle, and how do I do this? thank you |

Hi Lynda;
I have a few question. 1. What is "Ryon"? (I never worked on nozzle flows so, I am not sure if this word is specific to that field). 2. I am not clear about where the meniscus is in motion. Could you post a picture showing what is happening? Saideep |

Dear Iynda,
I think it would be better to describe closer what you are trying to simulate. A sketch of the geometry would be fine, and a graph of the results in question too.
