An Improved WENO-Z Scheme for Hyperbolic Conservation Laws with New Global Smoothness Indicator
The fifth-order WENO-Z scheme proposed by Borges et al., using a linear combination of low-order smoothness indicators, is designed to provide a low numerical dissipation to solve hyperbolic conservation laws, while the power q in the framework of WENO-Z plays a key role in its performance. In this paper, a …
