AI中文摘要:
我们提出并分析了一种强守恒的可杂交间断Galerkin有限元方法,用于求解带有Beavers-Joseph-Saffman界面条件的不可压缩Navier-Stokes与Darcy耦合问题。先验误差分析表明,速度误差不依赖于压力,且速度和压力均以最优速率收敛。这些结果通过数值算例得到了验证。
英文摘要:
We present and analyze a strongly conservative hybridizable discontinuous Galerkin finite element method for the coupled incompressible Navier-Stokes and Darcy problem with Beavers-Joseph-Saffman interface condition. An a priori error analysis shows that the velocity error does not depend on the pressure, and that velocity and pressure converge with optimal rates. These results are confirmed by numerical examples.
