I am looking to simulate fluid flow through a pipe with an external air flow across the surface of the pipe. I know this can be done but just not sure how to set it up. Can anybody help me out with this?
Perform as an external flow. If fluid inside is different from outside, then you will want to define this by using the fluid subdomain option in the tree (you have to click any face that touches that fluid). Then you'll want to define BCs for the internal flow. Attached is a simple example I whipped up, done in SW & Flow 2011 SP 3.0.
