本文用有限元法求解Navier-Stokes方程，研究了牛顿流体在平面和轴对称突扩区域的层流流动。结果巩固了文献中提供的信息，并提供了一个更广泛的图片如何膨胀比和雷诺数影响的再附着长度，下游位置的涡流和相对涡流强度在两个坐标系。
Laminar flow of a Newtonian fluid in planar and axisymmetric abrupt expansions is studied by solving the Navier-Stokes equations using the finite element method. The results consolidate information provided in the literature and provide a broader picture of how the expansion ratio and Reynolds number influence the reattachment length, downstream location of the eddy and the relative eddy intensity in both co-ordinate systems.
