Gearbox Comparison to Physical Test
I am doing a comparison to physical test data using a single gear rotating through a pool of oil. This is only for my own education at the moment. I think that the basics of my model are set up well (gear seems to be rotating correctly, oil volume seems to be correct, the oil is obviously interacting with the gear). However, I am having some trouble getting the oil to actually get dragged around by the gear. I simply see a cavity forming around the gear with only a tiny interaction between the gear and the oil.
If I were to guess, it looks like the pressure interaction between the solid particles and the fluid particles is too strong. The oil appears to be pushed radially outward instead of attaching to the gear.
Do you have any resources on which parameters that I can look into tuning to get this to match better? Are there any tutorials on this topic?
I am experienced with CFD, but new to DualSPHysics.
