Abstract：

Droplet　breakup　in　microconstrictions　is　an　important　phenomenon　in　industrial　applications.　This　work　aimed　to　investigate　the　droplet　breakup　in　the　square　microchannel　with　a　short　square　constriction　to　generate　the　slug　flow,　which　drew　little　attention　before.　Mechanism　analysis　indicated　that　this　breakup　process　included　the　shear-force-dominated,　squeezing-force-dominated,　and　pinch-off　stages.　Nonuniform　daughter　droplets　were　generated　in　the　constriction　with　their　interface　restricted　in　the　horizontal　and　perpendicular　directions　by　the　microchannel　walls.　The　average　relative　deviation　of　the　daughter　droplet　size　was　©　2022　American　Institute　of　Chemical　Engineers.
