    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    For external flows, inviscid flow provides a very close approximation to the solution for a viscous fluid outside the thin boundary layer at a solid surface. For internal flows, inviscid flow provides a very close approximation to the solution for a viscous fluid in the entrance region of the duct or channel, outside the wall boundary layer at the solid surfaces.
