“…The RTD curves become broader when the channel dispersion number, which is the Peclet number's reversal, increases, as shown in Figure 2A. [44][45][46] In the case of the twophase flow, when the flow rate of one phase increases, leaving the other unaltered, the residence time decreased, and the RTD curves become sharper due to the increment of the velocity of the phases (Figure 2B,C). When the height of the packed channels (uniform packing materials and the bed porosity) decrease, for a particular flow rate of the fluids, the velocities and the mixing properties of the phases increased, lowing the residence time, and making the RTD sharper (Figure 2B,C).…”
