Modeling Jet flow of Water in Air Atmosphere

Please login with a confirmed email address before reporting spam

Dear All
I am modeling the flow of jet (say water or similar liquid) in an atmosphere of air. The problem is very similar to the one in the model library (the inkjet example). However, my domain dimensions should be in cm instead of mm as in the example. When I change to the cm in the geometry and keep everything the same, the model does not solve. Does anyone have an idea what should be adjusted when growing in size on the domain? I was thinking of Reynlods number getting into the turbulent regime while I am using N-S, but I found it around ~ 100 so, I should be on the safe side in this regard.
Any advice would be highly appreciated.
Thanks
Ahmed

Having the same question/problem - but in µm-range and passing though a narrow orifice.
Any example models available? That would be great ;)
