摘要：采用修正Jeffreys模型来描述聚丙烯酰胺水溶液流变特性.首先用具有二阶精度的差分法与拟谱法求解幂率模型,分别与解析解进行比较,结果表明拟谱法具有极高精度.然后用拟谱法求解PAM水溶液在圆管中流动,得到速度分布、应力分布,为三维模拟作准备.
In this paper, we adopt the modified Jeffreys model to describe the rheological behaviors of Polyacrylamide aqueous solution. First, a comparison between the computational results of the pseudo-spectral method and the difference method with two-order accuracy of Power-Law model and analytic solutions, respectively, shows the former has a very high accuracy. Then it is used to solve the flow of PAM solution in a circular tube. The velocity and stress distributions obtained can be used for the three dimension numerical simulation in the future.
