摘要:
建立二维非定常Stokes方程的时间二阶精度的稳定化Crank-Nicolson (CN)有限体积元格式, 并给出其稳定化CN有限体积元解的误差估计。数值实验说明时间二阶精度的稳定化CN有限体积元格式比时间一阶精度格式更优越, 从而表明稳定化CN有限体积元格式对于求解非定常Stokes方程的数值解是有效可行的。
A stabilized Crank-Nicolson (CN) finite volume element formulation with time second-order accuracy is established for two-dimensional non-stationary Stokes equation. The error estimates of its numerical solutions are provided. Some numerical experiments are presented illustrating that the stabilized CN finite volume element formulation with time second-order accuracy is far more advantageous than that with time first-order accuracy, thus validating that the stabilized CN finite volume element formulation is feasible and efficient for finding the numerical solutions for two- dimensional non-stationary Stokes equation.
