In about a half century, a huge amount of data and knowledge has been accumulated from theoretical and experimental studies on micromixing. Nevertheless, those results are mostly composites of simplified theoretical and empirical models, and the true nature of interactions of flow inhomogeneity and micro-mixing with chemical reaction has not been fully unveiled. This article reviews the progress in micro-mixing study in chemical reactors to date. A few important topics related to the nature, experimental evaluation, and numerical simulation of micro-mixing are addressed.Some suggestions are given hopefully to motivate more chemical engineers to devote their efforts to better understanding of micro-mixing in chemical reactors.展开更多

Topics regularly covered include design and construction of structures(including wharfs,dike,breakwa-ters,platforms,mooring systems,etc.),instrumentation/testing(physical model and numerical model),materi-al research,structural/stress analysis.soil mechanics,sedimentation and wave dynamics. Sponsored by Chinese Ocean Engineering Society,the Journal will devote itself to strengthening academicexchanges,promoting cooperation in science and technology,and making contributions to the progress inocean engineering展开更多
