摘要:

血流模型保持稳态解,其中通量梯度非零但恰好被源项平衡。本文设计了具有这种平衡性质的高阶有限差分加权非振荡(WENO)方案,并同时保持真实的高阶精度。严谨的理论分析和广泛的数值结果均表明,所得到的方案验证了高阶精度,保持了平衡性质,并在光滑和间断解中保持良好的分辨率。

英文摘要:

The blood flow model maintains the steady state solutions, in which the flux gradients are non-zero but exactly balanced by the source term. In this paper, we design high order finite difference weighted non-oscillatory (WENO) schemes to this model with such well-balanced property and at the same time keeping genuine high order accuracy. Rigorous theoretical analysis as well as extensive numerical results all indicate that the resulting schemes verify high order accuracy, maintain the well-balanced property, and keep good resolution for smooth and discontinuous solutions.
