4.1.4. A limited CFD comparison between the Nye tray and
the same sieve tray
Figs. 17 and 18 give the liquid velocity vectors and weep rates,
respectively, for the Nye tray and the same sieve tray in Q=0.0105
(m3/s), FS=0.392 m/s
(kg/m3)0.5, and \(h_{w}=5cm.\) As
can be noticed, there is a negligible difference between the weeping
rate downstream and upstream of the sieve tray but concerning the Nye
tray, the difference between the weeping rate downstream and upstream of
the Nye tray is massive. Furthermore, the total weeping rate for the Nye
tray is close to the total weeping rate of the sieve tray but slightly
higher. Fig. 17 shows that the velocity of water drops is almost uniform
along with the Nye tray, where this parameter is ununiformed along with
the sieve tray.
