“…Therefore, attempts have been made to carry out 3D multiphase simulations based on a simplified or a detailed 3D geometry model. Liu et al simulated a liquid jet impacting on a typical hydrophobic or a hydrophilic wire mesh layer, using the moving particle semi-implicit (MPS) method. The stability of the MPS method still needs a further improvement.…”

To understand the mechanism of droplet dispersion, the behaviors of a droplet impacting on a single-layer wire mesh were investigated by computational fluid dynamics simulations with a detailed 3D geometry of real woven wire meshes. After validating the simulation data, the effects of different operating conditions on the liquid dispersion were systematically studied. The results showed that the cone angle of dispersion of the hydrophobic wire mesh increased by 37–103%, compared with the hydrophilic wire mesh. A more accurate dispersion angle can be obtained by the 3D simulation, compared to the previous high-speed imaging experiments with 2D photographs. The ratio of dissipated energy of the droplet impacting on the hydrophobic wire mesh was 29% lower than that on the hydrophilic wire mesh, allowing us to reveal the dispersion intensification mechanism of droplet breakage. This study provides insights into the droplet impaction and dispersion on the wire mesh packing, which can guide reactor design and optimization.

“…The results showed that liquid impacting on the hydrophobic wire mesh had better dispersion performance, forming a larger cone angle of dispersion with smaller daughter droplets. Liu et al 19 simulated the process of liquid jet impacting on hydrophobic and hydrophilic wire mesh. The surface hydrophobicity of wire mesh could intensify the liquid dispersion and generate independent fine liquid jets under the wire mesh.…”

Liquid dispersion by impacting on wire mesh benefits many mass transfer processes. However, most of studies focused on the dispersion behaviors of liquid impacting on a one-layer wire mesh. In this work, the intensification of droplet dispersion by impacting on multilayer wire mesh was investigated as well as considering the influence of surface wettability. The dispersion characteristics (cone angle of dispersion θcone and average diameter of daughter droplets d avg) were systematically analyzed. θcone enlarged by 44% and d avg decreased by 12% on average when increasing the water contact angle of the wire mesh from α-70° to α-155°. Empirical correlations for predicting θcone and d avg were proposed. The predicted values agreed well with the experimental data. The intensification of liquid dispersion by using multilayer wire mesh was applied in the inner cavity zone of a rotating packed bed (RPB), leading to a significant improvement of gas–liquid mass transfer performance.
