4.1.3. CFD and experimental results at Q=0.0158
(m3/s)
Figs. 13 and 14 present 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=0.0158
(m3/s) flow rate. However, at high liquid rates, it is
observed that changing the weir height from 5 to 7.5 cm has only a
slight effect (Figs. 13 and 14). Evidently, weeping rates in the
downstream are higher compared to the upstream for this flow rate. It is
observed that different weeping rates in downstream and upstream of the
tray decline with an increase in the gas flow rate. Figs. 15 and 16
verify the results of Figs. 13 and 14.
