By using the method of coordination transformation and expandedness Fourier series, an analytic solution is obtained from studying the Newtonian fluids laminar flow in eccentric anulus.

采坐标变换和函展开成傅立叶方法,推导出了牛顿流体偏心环轴向流动速度场严格学.

Numerical simulations of laminar flow separation and reattachment occurred in an annular backstep passage are performed by the SIMPLER algorithm.

SIMPLER算法对流过环形后台阶通道内层流分离和再附着进行了值模拟。
