4.1.2. CFD and experimental results at Q=0.0105 (m3/s)
Figs. 8 and 9 illustrate the liquid weeping rate for each tray half as a function of Fs respectively at\(h_{w}=5cm\mathbf{\ }\)and\(\ h_{w}=7.5cm\mathbf{\ }\) for Q=0.0105 (m3/s) flow rate. Raising the liquid flow rate results in an increase in the weeping rate for outlet and inlet halves of the tray. For a low gas velocity range, the flow regime has a tendency toward the dumping or channeling weeping for both parts of the tray. Also, it is obvious that weeping rates in the downstream are more than those of the upstream for this flow rate and weir height is effective in the amount of tray weeping. Overall, increasing the weir height results in a subsequent increase in the clear-liquid height and an increase in the weeping rate (Figs. 8 and 9). Figs. 10 and 11 and 12 confirm these issues.
