ABSTRACT:
A conduit for carrying fluid in a downstream direction includes a diffusing section. Downstream extending convolutions in the wall of a diffusing section energize the boundary layer and delay boundary layer separation from the wall surface of the diffusing section or permit an increase in the diffusion angle without the occurrence of separation. Such convolutions are particularly useful when rapid diffusion is required in a short distance, such as in the diffusing section of automotive catalytic converter systems. Such a system carries engine exhaust products from a small, cylindrical pipe into a typically larger elliptical cross-section catalyst filled portion. The convolutions help to more uniformly disperse the exhaust gas throughout the catalyst bed using a relatively short diffusion section.
