弯道水流的动力特性主要集中在水面横比降、横向环流、流速重分布等方面。

Bend flow momentum characteristics is mainly concentrated in the surface sloop, cross circulation and the velocity re-distribution.

弯道环流形成的城陵矶河段莲花塘断面横向水位落差是防洪中非常关心的问题之一。

Water level difference crossing Lianhuatang section reduced by circulation flow is one of the most important problem in flood control.

模拟结果表明，在L型定向风帽流化床中，颗粒存在顺时针方向的循环流动，因此床料的横向混合特性较好。

The simulation result indicates that there is clockwise particles circulation in fluidized beds with L-type wind caps.
