VISCOUS FLOW IN HELICAL PIPES WITH NARROW ANNULAR CROSS SECTION

    摘要
  • 摘要: 根据张量分析,建立了非正交的曲线柱坐标系巾的N-S方程,采用摄动法求解环形截面螺旋管道内的粘性流动。结果表明:环形截面上存在二次流

     

    Abstract: The Navier-Stokes equations are established for a nonorthognal coordinate-system based on tensor analysis. The zeroth-, the first- and the second-order (t = 0) analytic solutions are obtained for fully developed flow in helical pipes with narrow annular cross section using a perturbation method. It is found that there is a secondary flow on the annular cross section.
