Flow dynamics and mixing past pairs of confined microfluidic cylinders
Résumé
Mixing induced by pairs of microfluidic cylinders is investigated experimentally. Micro Particle Image Velocimetry (lPIV) and micro Laser Induced Fluorescence (lPLIF) are employed. Steady and unsteady flow regimes and various arrangements (tandem, staggered) are explored. Mixing enhancement is found to depend strongly on cylinder arrangement and flow regime. Staggered arrays perform better at low Reynolds number while tandem ones under conditions of vortex-shedding.
