In this paper, three iterative methods (Stokes, Newton and Oseen iterative methods) based on finite element discretization for the stationary micropolar fluid equations are proposed, analyzed and compared. The stability and error estimation for the Stokes and Newton iterative methods are obtained under the strong uniqueness conditions. In addition, the stability and error estimation for the Oseen iterative method are derived under the uniqueness condition of the weak solution. Finally, numerical examples test the applicability and the effectiveness of the three iterative methods.
本文提出、分析并比较了基于有限元离散化的用于定常微极流体方程的三种迭代方法(斯托克斯、牛顿和奥森迭代方法)。在强唯一性条件下得到了斯托克斯和牛顿迭代方法的稳定性和误差估计。此外,在弱解的唯一性条件下推导了奥森迭代方法的稳定性和误差估计。最后,通过数值例子检验了这三种迭代方法的适用性和有效性。
