For the Z-shaped micro-channel micromixer by convective mass transfer, the inlet velocity has the very tremendous influence to the mixing, but the diffusion coefficient\'s impact is small to the mixing. Micromixer with S/W=2 structure can make the good mixing performance under each kind of speed condition. The smaller the angle of corner of Z-shaped micro-channel micromixer is, the higher the mixing performance is.

对于以对流传质为主的Z型通道微混合器，(来源：ABC论文53网www.abclunwen.com)入口速度对混合有很大的影响，而扩散系数对混合的影响较小。S/W=2在各种速度条件下均能取得较好的混合效果。Z型通道微混合器的转角越小，其混合性能越高。
