- Looking for references analyzing fluid drainage along the outside of an inclined cylinder

Asking on behalf of a colleague who is studying rainwater transport/drainage in the context of plants (trees, mostly):

There's a lot of published work analyzing the flow of fluid within a tube, or along an interior corner. I can't seem to find much of anything about the flow of water along the outside of a cylinder- think rainwater on a cable. Clearly interfacial energy has a lot to say about how much water is transported along the cable and how much drips off onto the ground. I guess a pendant drop analysis is a reasonable starting point, but the contact line isn't pinned as the usual case.

Has anyone worked out the fluid dynamics?

Just hoping someone can point us in the right direction for a literature search. Thanks in advance!
