references for mixer scale-up?
(OP)
I'm looking for any good references or rules-of-thumb for mixer scale up. Are there any rules of thumb for power input required to produce similar mixing intensity in vessles of larger sizes? Apart from being a function of viscosity, etc, is there a simple relationship between power input, assuming similar tank design with respect to baffles and geometry. I know it is very difficult to get uniform mixing in tanks of larger size, but could someone shed some light on the physics behind this?

You have gotten very good advice so far. I have read the articles from Chemineer and they are good. Fxm is right in that if you have similar geometry then you can look at W/kg as a rough guide to scale up. (I generally use 5HP/500gallons. But we use very violent mixing.)
A good book that I have on mixing called Mixing for the process industries Robert J. McDonough.
If you come back with a little more details we can give you a rough idea.
