Mixing characteristics for the single and air‐water two‐phase flows in miniaturized parallel multichannel‐based devices

Abstract Investigation on the miniaturized parallel multichannel‐based devices packed with glass beads to improve the mass exchange execution is the critical focal point of the current study. One of the essential parameters to specify the miniaturized devices' flow distribution is the residence time distribution (RTD). In the present context, the RTDs of a liquid tracer were investigated for the air‐water multiphase flows (concurrent) across the multichannel‐based miniaturized devices (comprising of 11 similar dimensional parallel channels). The devices were variable in height and packed with glass beads. The conductivity estimations generated the RTD curves and were addressed by the axial dispersion model (ADM). The fluid‐flow rates differed within the range of 5–23 ml min −1 . The axial dispersion coefficients and the rate of the specific energy dispersion were investigated. The effects of pressure difference and geometry on the hydrodynamic attributes and mixing properties were well‐illustrated, and the new correlations were suggested.
