“…Along this line, recently, studies on the interactions among multiple jets have been pioneered by a few researchers. Roger et al 17 used the large eddy simulation (LES) approach and the particle image velocity (PIV) measurements to study the interactions between twin square jets side-by-side. Gui et al 18 used the lattice Boltzmann equation (LBE) method to simulate the coherent vortex motions and interactions of jets in crossflow with the Reynolds number ranging from 1000 to 3000.…”

We investigated and compared the turbulent characteristics of two-liquid mixing in single-orifice and multiorifice-impinging transverse (MOIT) jet mixers through large eddy simulations and the planar laser-induced fluorescence technique. Our focus is on evaluating the roles played by the interactions among the jets in the mixing intensification. The turbulent vortex structures, time-averaged mean concentration distributions, root-mean-square of the concentration fluctuations, probability density function, and power spectral density are discussed. For the MOIT jet mixer with large jet-to-crossflow velocity ratios, direct impingement of the jets enhances the mixing by speeding up the evolution of the counter-rotating vortex pairs, resulting in reduction in the vortex scale, increasing the vortex magnitude, and homogenizing the vortex distribution. The effect of the mixer scale-up on the turbulent characteristics was also studied. Moreover, we selected a specific MOIT jet mixer to perform optimization of the orifice number and diameter of the jet flow with fixed other parameters.
