And the bottom adjacent to the lower flowturning slow, centrifugal force is small, the gravity flow from the outer edge of the inner edge, resulting in secondary reflux.
与槽底相邻的下层水流回转速度慢，离心力小，在重力作用下从外缘流向内缘，产生二次回流。

Different types of cracks appear during the LF6 alloy flowturning at room temperature. Combining the theoretical analysis results, the reasons of producing cracks were explained in detail.
Under normal circumstances should be set in the first mesh upstream flowturning point, the water before near the river, you can control the mainstream, play a role in the light of its general trend.
