High order weighted essentially nonoscillatory WENO-η schemes for hyperbolic conservation laws
2014
Journal of Computational Physics
In [8] , the authors have designed a new fifth-order WENO finite-difference scheme (named WENO-η) by introducing a new local smoothness indicator which is defined based on the Lagrangian interpolation polynomials and has a more succinct form compared with the classical one proposed by Jiang and Shu [12] . With this new local smoothness indicator, higher order global smoothness indicators were able to be devised and the corresponding scheme (named WENO-Zη) displayed less numerical dissipations
