摘要：

Based　on　the　principle　of　asymmetric　split　and　recombine,　this　paper　has　adopted　a　numerical　simulation　for　the　optimized　micromixer　with　dislocation　sub-channel　to　get　mixing　performance　and　taken　the　mixing　index　as　a　measurement　index.　The　results　show　that　when　Re　is　ranging　from　1　to　80,　parameters　of　geometric　structure　affect　the　mixing　index　of　the　micromixer　obviously　and　the　mixing　index　is　improved　if　the　dislocation　sub-channel　is　set　in　the　major　channel.　Considering　the　mixing　performance　and　the　pressure　drop　in　the　sub-channel,　the　mixing　index　of　asymmetric　split　and　recombine　micromixer　with　dislocation　sub-channel　can　be　increased　to　86%　when　the　geometric　structure　parameter　of　the　dislocation　sub-channel　is　w3/w4=1.
