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.
