Swirl-induced improvement of turbulent mixing: laser study in a jet-stirred tubular reactor

Abstract : Laser measurements of local velocity and concentration in a swirling-jet-stirred tubular reactor under turbulent regime provide a complete analysis of hydrodynamics and mixing processes. Comparisons with the non-swirling case show how swirl promotes turbulent mixing. Local velocities are obtained by laser Doppler velocimetry. Local mixing characteristics (mean concentration and segregation) are measured by laser-induced fluorescence.
