摘要：
Detailed experimental measurements have been reported in an S-shaped diffusing duct having an area ratio of 2.0 with an inlet aspect ratio of 6.0. This duct was fabricated by joining two 90 degrees identical diffusing ducts with an offset of 382 mm. The measurements show that the vortical motions generated in the first half of the duct change their direction of rotation beyond the inflection point. A small pocket of flow reversal is seen at the inflection plane. The flow at the exit of the duct is seen to be fairly uniform. The overall pressure recovery in comparison to a straight diffuser is low.
