“…The flume experiments conducted by Ben Meftah et al [12] and Malcangio et al [13] have been recognized by many scholars [15,17,18,[31][32][33]. In this study, the model used is similar, but with reasonable adjustments on the models of Ben Meftah et al [12] and Malcangio et al [13], as presented in Figure 1.…”

“…Based on the experiments of Malcangio et al [13] and Ben Meftah et al [12], Gao et al [7] and Xiao et al [17] analyzed the spatial and temporal evolution of the vortex and the influence of dominant frequency on the vortex structure by using the large eddy simulation (LES) model, which further illustrated the role of vegetation on jet development. Teng et al [18,19] investigated the effect of different vegetation arrangements on the lateral emission jet by using the particle image velocimetry (PIV) technique. Their experiments revealed the diamond-shaped arrangement of vegetation to have a stronger deceleration effect than the other arrangements.…”

Vertically discharged multiple jets in crossflow is a common form of wastewater discharge. The presence of vegetation in the flow channel complicates the hydraulic characteristics of jets. The realizable k-ε turbulent model is used to simulate the flow, turbulence, and vortex characteristics of multiple jets with different spacing and jet-to-crossflow velocity ratios, to study the flow characteristics and vortex structure of multiple jets in a vegetated channel. The results reveal that vegetation inhibits the development of a counterrotating vortex pair. The jets with a low jet-to-crossflow velocity ratio are concentrated near the flow symmetry profile by the dual constraints of ambient flow and vegetation. The jets gradually spread outward and the counterrotating vortex pair become more obvious when the jet-to-crossflow velocity ratio increases. Vegetation reduces the shading effect of the front jet on the rear jet by accelerating the dissipation of shear layer vortices. The influence of the front jet on the rear jet decreases as the spacing increases.
