研究了二维和三维非定常微极流体方程的速度校正投影方法.采用一阶和二阶后向差分格式进行时间离散及协调有限元进行空间离散,给出了一阶和二阶时间半离散速度校正投影方法的无条件稳定性和一阶时间半离散格式的误差估计以及相应的全离散格式,证明了一阶全离散格式的无条件稳定性.最后,通过数值算例验证了该方法的有效性.
The velocity-correction projection method for the 2D/3D time-dependent micropolar fluid equations is considered. In this method
the first-order and second-order backward difference schemes are applied for time discretization and conforming finite element is adopted for spatial discretization. The unconditional stability of the first-order and second-order time semi-discrete velocity-correction projection methods are given
and the error estimation of the first-order semi-discrete scheme is analyzed. The stability analysis of the first-order fully discrete scheme is also given. Finally
several numerical examples are presented to show the efficiency of the proposed method.
