I am designing a mixer for some 3D printer resin vats and am stuck on the best way to approach the problem. At the beginning I thought I should use three mixers in a line, all spinning in opposite directions so as to compliment each other (like an egg beater but with an extra mixer). But the more I research the less sure I am that this would be better than one, large mixer. Without doing a complex CFD I have no way of knowing which would be better.
I am hoping that someone with a bit more knowledge on fluid mechanics can inform me on the pro's and con's of each, and which approach would be better to mix fluid?
EDIT: I appreciate all the answers but they seem to avoid the question. I would just like to know the advantages of using a single mixer vs multiple mixers with a slightly viscous fluid.
