摘要:

我们提出了一种虚拟元方法,用于求解与热方程耦合的对流Brinkman-Forchheimer问题。该耦合模型允许热扩散和粘度作为温度的函数。在标准离散假设下,我们证明了所提数值格式的适定性。在解的适当正则性假设下,我们还推导出最优误差估计。最后,我们使用不同网格族进行了一系列数值实验,以补充我们的理论结果。

英文摘要:

We develop a virtual element method to solve a convective Brinkman-Forchheimer problem coupled with a heat equation. This coupled model may allow for thermal diffusion and viscosity as a function of temperature. Under standard discretization assumptions, we prove the well posedness of the proposed numerical scheme. We also derive optimal error estimates under appropriate regularity assumptions for the solution. We conclude with a series of numerical tests performed with different mesh families that complement our theoretical findings.
