A multivortex device is provided comprising a series of adjacent plates with specially designed grooves and perforations which, when mounted transversely of a uniform fluid flow in a duct, results in the formation of numerous small adjacent flow vortices either all rotating in the same direction (co-vortices) or adjacent vortices rotating in opposite direction (countervortices). The fluid at the peripheries of adjacent co-vortices move in opposite directions and friction converts their rotational kinetic energy into turbulence within a few vortex diameters downstream from the multivortex device. The fluid at the peripheries of adjacent counter-rotating vortices move in the same direction, such that they roll upon one another substantially without friction and persist for many vortex diameters downstream from the multivortex device. The adjacent plates of the multivortex device can be provided with additional grooves and passageways which allow a second and/or third fluid to be introduced within each vortex. The high speed rotation of the first fluid can be used to act on the second and third fluids. A turbulent co-vortex field can be used to induce rapid mixing and chemical reaction, while a countervortex field can be used to remove particulates from the flow.
