ENHANCED TURBULENT MIXING

摘要

A flow directing apparatus for directing fluid flowing therethrough includes a flow body defining an upstream facing inlet surface and an opposed downstream facing outlet surface with a bore defined through the flow body. The bore includes an inlet portion of the bore extending in a downstream direction from an inlet where the bore meets the inlet surface. An intermediate portion of the bore extends in a downstream direction from the inlet portion of the bore. A backstep portion of the bore extends downstream from the intermediate portion of the bore to an outlet where the bore meets the outlet surface. The intermediate portion of the bore has a cross-sectional flow area that is smaller than that of the inlet portion and smaller than that of the backstep portion to provide a backward facing step in flow area for flow through the bore.

1. A flow directing apparatus for directing fluid flowing therethrough, comprising:
a flow body defining an upstream facing inlet surface and an opposed downstream facing outlet surface with a bore defined through the flow body from the inlet surface to the outlet surface, wherein the bore is configured to direct fluid flowing therethrough and includes: an inlet portion of the bore extending in a downstream direction from an inlet where the bore meets the inlet surface; an intermediate portion of the bore extending in a downstream direction from the inlet portion of the bore; and a backstep portion of the bore extending downstream from the intermediate portion of the bore to an outlet where the bore meets the outlet surface, wherein the intermediate portion of the bore has a cross-sectional flow area that is smaller than or equal to that of the inlet portion and smaller than that of the backstep portion to provide a backward facing step in flow area for flow through the bore.
