Calculation results show that the code can predict inner flow-field of turbomachinery accurately and gas separation, as well as reattachment appeared in this turbine stage.
The re-circulation and reattachment process in backward-facing step flow is investigated using large eddy simulation (LES).
应用自主开发的大涡模拟程序数值模拟研究了后台阶流动中再附着过程的演变。

When the flow kept with turbulent state, the relationship between reattachment length and step ratio is obtained, which agrees well with the experimental visualization results.
