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