Mixing efficiency and energy consumption for five generic microchannel designs

Experimental study of efficient mixing in a micro-fluidized bed

“…This quantity is shown in Figure 7(a) for the particle-free channel and µFB as a function of the inlet fluid velocity. The ME of the particlefree channel appears to be little affected by superficial velocity, consistent with both our previous studies [26,54] and the fact that transport will be essentially controlled by molecular diffusion. The µFB results indicate that it is not as effective as the particle-free channel at superficial velocities below around 150 µm/s.…”

Design and evaluation of an easily fabricated micromixer with three-dimensional periodic perturbation

“…Using theoretical analysis, Falk and Commenge carried out a comparison of several micromixers in terms of mixing time [25]. From an experimental point of view, the mixing quality of typical micromixers was compared while maintaining the same concentration protocols [23,26]. A similar experimental comparison method was adopted in the current study.…”

Test Reactions to Study Efficiency of

“…They extended a method of using iodine/iodide reaction system together with IEM mixing model to study microreactors. The method has become very popular and since then frequently applied to examine all kinds of microreactors, see for example (Guo et al, 2013;Kashid et al, 2011;Su et al, 2011) and (Aubin et al, 2010;Kölbl et al, 2008;Panic et al, 2004) for earlier applications of Villermaux-Dushman reaction. Falk and Commenge (2010) have shown how to identify mixing time, and how to relate it to operating parameters such as Reynolds number of the flow and the specific power (dissipation of mechanical energy per unit mass of fluid).…”
