Mechanism to reduce turning losses in angled conduits

摘要

Downstream extending convolutions (52) disposed on the inside corner (72) of an angled conduit (50) eliminate or reduce the two-dimensional boundary layer separation region (44) thereby eliminating or reducing the pressure losses associated with the separation region (44). The convolutions (52) may be formed into either the angled conduit wall or in an insert (200) which is positioned on the inside corner surface of the conduit.
