在本文中，我们构造了二维非结构网格（三角形）上有限体积格式的高阶加权本质无振荡格式。我们提出了三阶计划使用的线性多项式和四阶计划使用的二次多项式的组合。数值算例表明了该方法的准确性和鲁棒性。(C)北京：科学出版社.
In this paper we construct high-order weighted essentially non-oscillatory schemes on two-dimensional unstructured meshes (triangles) in the finite volume formulation. We present third-order schemes using a combination of linear polynomials and fourth-order schemes using a combination of quadratic polynomials. Numerical examples are shown to demonstrate the accuracies and robustness of the methods for shock calculations. (C) 1999 Academic Press.
