“…where μ is the viscosity of the gas phase. According to Miller, [37] the effect of the relative plate thickness on the pressure drop can be presented by the following empirical formula: From Equations (12) and (13), it can be seen that the difference in the hole distribution method is mainly reflected in the differences of the exponent of l/ h and d 0 /h, and this is in accordance with the simulated results. The ranges of the test parameters are as follows: 510.3 ≤ Re s ≤ 11 046.6, 0.115 ≤ α ≤ 0.176, 0.107 ≤ t/d 0 ≤ 0.250, 1.212 ≤ l/h ≤ 1.333, and 0.571 ≤ d 0 /h ≤ 0.606.…”

“…[12,13] CFD technology has been widely used in researching the hydrodynamic process of the fluid in complex column interiors. [9,12,[14][15][16][17][18][19] It can not only provide a realistic picture of the internal flow field and critical hydrodynamic parameters for the design and performance analysis of the column, [12,14,20] but it can also enable changes in the geometric parameters of the interiors to be made using the single variable method and simulates the conditions where experiments cannot be conducted. [18] Tang et al [9] investigated the flow behaviour of single gas flow through a tridimensional rotational flow sieve tray using CFD simulation with the realizable k-ε turbulence model and verified the simulated results by comparing them with the experimental pressure drop and velocity results, respectively.…”

Sieve plate packing is a newly developed packing that has been used in several industries due to its simple structure and operating flexibility, and no liquid flooding. In this work, first, systematic experiments were conducted to measure the pressure drop of gas flow through six sieve plate packings. The results indicated that the geometric characteristics of the packing have complicated effects on the pressure drops. Based on this, CFD simulations on the gas flow field were conducted using the realizable k‐ε model, and flow behaviours such as the pressure drop, pressure nephogram, and velocity distributions within different packings were obtained. The simulation results clearly showed interesting flow patterns, including the contraction and expansion of the gas stream through the sieve hole, the flow separation on the sharp edge of the hole, and the vortexes formed when gas impacts the downstream plate. By comparing the flow patterns and the pressure drop under different packings operating at different conditions, the effects of the geometric characteristics of the packing on the pressure drop could be clearly distinguished from the flow behaviours, so that the variations in pressure drop with various packing structures were clearly indicated. Finally, based on the experimental data and the simulated results, correlations for the prediction of the pressure drops were proposed. This work will provide a useful basis for understanding the flow behaviour of gas and liquid two‐phase flow in sieve plate packing.

“…Li et al 19 developed a CFD model to visualize the gas−liquid flow and distribution on a Glitsch V-1 valve tray using the Eulerian multiphase model. CFD simulations of Zarei et al 12 and Ma et al 20 also used the Eulerian multiphase model. Alizadehakhel et al 21,22 used the volume of a fluid multiphase model to examine the gas−liquid interface and pressure drop of In this study, the OBP of float valve trays was predicted using a numerical mesoscale numerical method, viz., the lattice Boltzmann method (LBM), for the first time.…”

“…Some scholars studied the hydrodynamic simulation of valve trays. [22][23][24][25][26] Abbasnia et al [27] investigated the state of mass transfer and efficiency of sieve and Nye trays for a methanol-normal propanol system. Distribution of methanol compositions across the trays was obtained for four different average methanol compositions.…”

Nye tray vs sieve tray: A comparison based on computational fluid dynamics and tray efficiency

Nye and sieve trays were hydrodynamically simulated and compared. The simulations were performed in a Eulerian-Eulerian framework under unsteady (transient) conditions at industrial scale. Conducted on an air-water system, the simulations included three dimensions and two phases. The velocity distribution across the tray, the height of clear liquid, the froth height, and the pressure drop were investigated and compared with experimental data. Péclet number was calculated using hydrodynamic and geometric parameters. The tray efficiencies were also predicted to further compare the two trays. The results showed that the liquid flow was steadier on the Nye tray rather than the sieve tray, possibly because of the special structure of the liquid and gas inlets for the Nye tray.
