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.
