Abstract

Control of mixing in turbulent flow may lead to considerable improvement of efficiency, safety and performance of various technological devices. In so-called passive control methods, shapes of control elements (bluff-bodies, swirlers, etc.) are often a result of trial-and-error based on geometrical modifications. In the present study we apply passive control to enhance mixing of fuel issuing from a pipe into a hot co-flowing stream. Near the outlet of the pipe plates with polygonal orifices are mounted. The role of these objects is to intensify mixing of large and small scales which potentially will lead to better mixing characteristics between the fuel and co-flow downstream of the pipe exit.
