Interesting. Could you please share some details regarding the grid size, type of elements used and the total cell number? I 'm working on something similar and I would appreciate to have some references. Thanks
This VOF simulation requires an extremely fine grid and a relatively small time step in order to resolve the flow in detail without adaptive methods. In this case, an unstructured two-dimensional grid with almost 400000 cells (polygonal and prism-layer cells) was used. The average size of the cells in the core was 0.16 % of the characteristic length (diameter of the flow domain). Ten prism layers with a total thickness of 0.08 % in relation to the characteristic length were used on the wall. The size of the time step was 0.2ms. The VOF model was used without the optional sharpening factor. I hope this is helpful.
Thanks a lot taking the time to answer my question. Is is ineed helpful look at the video and also to understand the grid resolution. I've done something similar in 2D with around 500k cells and VOF, in StarCCM+. For me was interesting to see that by using the tria mesh the results seemed more realistic than by using poly mesh. Thanks again and good luck with your projects.
nice
