recommendations! Published in 2017 at "International Journal for Numerical Methods in Fluids"

DOI: 10.1002/fld.4401

Abstract: Summary The weighted essentially nonoscillatory scheme is improved by introducing new smoothness indicators that evaluate the interactions among the classical smoothness indicators suggested by Jiang and Shu. The effect of the key parameters in the… read more here.

DOI: 10.1002/fld.4855

Abstract: This article presents an improved fifth‐order finite difference weighted essentially nonoscillatory (WENO) scheme to solve Hamilton‐Jacobi equations. A new type of nonlinear weights is introduced with the construction of local smoothness indicators on each local… read more here.

DOI: 10.1002/fld.4926

Abstract: A new simple and generic framework is proposed to construct nonlinear weights for third‐order weighted essentially nonoscillatory scheme (WENO) reconstructions. It is done by imposing necessary conditions on nonlinear weights to get a nonoscillatory WENO… read more here.

DOI: 10.1080/10618562.2020.1754403

Abstract: The resolution and robustness properties of a numerical scheme are two mutually restricted aspects for the detailed simulation of complex flows. In the present paper, an improved seventh-order finite difference weighted essentially non-oscillatory scheme (WENO-PR)… read more here.
