中文摘要：
对平面内非对称圆形通道、扇形通道及错位通道3种不同结构类型的微混合器的混合特性进行了数值模拟和分析，讨论在不同雷诺数下，通道几何结构参数对微混合器混合强度及通道压力损失的影响．研究结果表明：在雷诺数大于10时，3种类型微混合器混合强度均随雷诺数增大而增大；在不同雷诺数下，错位通道微混合器混合效果最佳，但其压力损失会相对增大．
英文摘要：
Numerical simulations and analyses were presented on mixing performance for three different structural micromixers which include ones with circular sub-channel, fan-shaped sub-channel and dislocation sub-channel, respectively. For different Re, the mixing intensity and pressure loss of micromixer were influenced by the geometric structure parameters of the channels. The results show that when Re is more than 10, the mixing intensity of three different micromixers increases as Re increases. In addition, for different Re, the micromixer with dislocation sub-channel acquires the optimal mixing performance, but the pressure loss increases relatively.
