A third order ENO finite volume method for hyperbolic conservation laws on unstructured triangular mesh is introduced.In order to obtain the third order accuracy on spatial discretization,a weighted quadratic interpolation is constructed on every triangular mesh.Two point Gauss quadrature formula is also used on each edge of every triangular mesh and the third order TVD Runge-Kutta method is used for time discretization.The numerical order of convergence and the numerical result of a mesh 3 wind tunnel with one step are given.
摘 要 基于双曲型守恒律方程,对非结构三角形网格给出了一种ENO(Essentially Nonoscillatory Scheme)型有限体积格式,方法的主要思想是先对每一个三角形单元构造一个加权的二次插值多项式,而在计算交界面的流通量时采用了两点高斯积分公式以保证格式的整体精度,时间离散采用三阶TVD Runge-Kutta方法。
