Abstract:
A method for enhancing fluid mixing, the method comprising the operations of:(a) configuring a duct to have an effective outer wall, an effective inner wall, a cross-sectional shape, a first cross-sectional area and an exit area, the first cross-sectional area and the exit area being different in size; and (b) generating a first flow region at the first cross-sectional area between the effective outer and inner walls, by a flow generator, the first flow region having a total pressure and a speed equal to or greater than a local speed of sound, the first flow region resulting in a second flow region subjected to a positive streamwise pressure gradient in proximity of the exit area, the second flow region being mixed with at least an adjacent fluid; wherein configuring the duct comprises configuring the duct to have an annular or oblong cross-sectional shape.
