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.

采用坐标变数展开成傅立叶级数的方法,推导出了牛顿流体偏心环轴向流动速度场的严格数学解析解.

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

用SIMPLER算法对流过环形通道内的层流分离再附着进行了数值模拟。
