Moreover, flow distribution was also calculated by free-vortexflow pattern and compared with that by iso-reaction coefficient flow pattern. Relative evaluation …
同时还对自由涡流型进行了计算，把这两种流型的计算结果作了比较，并对这两种流型的风扇进行了评价。

Then basing on the free-vortex equation, potential equation and stream function of flow are achieved by mathematical analyze, and solving these equations gives flow fields.
从自由涡运动方程出发，推导出管内流场的势函数和流函数方程，获得了管内流场的数学分析解；

The contrast of new designed blade with the original one is made in the design of freevortexflow combining with aft-loading profile.
