In this paper,the development of fluid mechanics and computational fluid dynamics software FLUENT is sum-marized,and discuss the development of numerical flume.Due to the numerical flume has theunique advantages of low cost,good repeatability,easy control of conditions,so the momentum of development.According to the lots of research at home and abroad,although the time of the concept of numerical flume is not long,but it developed rapidly,so the estab-lishment of efficient numerical flume in fluid mechanics is a subject worthy of study.
