Maybe. But I tend to think of a hub as a kind of homogenous mixing point. E.g. a bicycle hub has all the spokes connnecting to the hub at equal distances. For water flow, something like a sewage treatment plant might have a reservoir into which pipes or canals feed, where the pipes/canals are all roughly the same length and enter the reservoir at similar distances and (possible) flow rates (pipe sizes, etc.).
A river confluence, for example, might have 2 streams merge at one point, then a 3rd stream merge in later, a stream merging with a big stream, etc. So, there's some implication that the merging/branching is heterogeneous. Abstracting the detail of such a thing would definitely make it some sort of "mixing hub". But it wouldn't be "well-mixed" if you zoomed in. All concrete hubs (e.g. Unilever in a supply chain model or whatnot) *do* have some sort of internal structure you can see when you zoom in, though. So, maybe a qualified phrase like "fractal hub" would work?
