A CFD investigation of mixing profiles within a micro-coiled flow inverter

Background/Objectives: Due to the low Reynolds number (Re) in microfluidic domain, the predominant laminar flow might inhibit effective mixing in micro-Coiled Flow Inverter (mCFI). Fluid dynamics within the mCFI was simulated with Computational Fluid Dynamics (CFD) software to investigate the mixing...
