Does anyone have an idea how to model the flow of impure water in a filter membrane?
Specifically, filtering out sand particles (approx. 100 microns) using a square plate that has 50 microns sizes.
I have inserted the square filter into a 200 micron tube for the computation area in assembly.
1. When I initially use the wizard, I used water as reference.
2. I am unsure of the boundary conditions. Are there any good thumb rule for this?
(I used the bottom part of the tube as the initial flow in with a Total pressure of 2 atm and the top part with a environmental pressure of 1 atm, such as that I am pushing the model in a tank of water)
3. Once the calculation is complete I proceeded to the particle study. Am I suppose to define to a new solid (call it "sand") or can I just use iron, for example, and change the particle size to 100 micron, will that work?
