초록

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 pro...

청구항

A device for carrying a fluid in a downstream, principal flow direction, comprising wall means defining a diffusing section for decreasing the velocity in the principal flow direction and increasing pressure, said diffusing section having means defining an inlet and an outlet, the inlet cross-sectional flow area being less than the outlet cross-sectional flow area, said diffusing section wall means having a fluid passage defining surface extending from said inlet to at fluid passage defining surface extending from said inlet to at least said outlet, said...
