Published in 2019 at "International Journal for Numerical Methods in Fluids"

DOI: 10.1002/fld.4739

Abstract: In this paper, we have proposed a new problem independent discontinuity locator for hybridization. Along with this, a new global smoothness indicator is proposed. The hybrid weighted essentially nonoscillatory (WENO) scheme works on the principle… read more here.

Published in 2024 at "International Journal for Numerical Methods in Fluids"

DOI: 10.1002/fld.5314

Abstract: A modified fifth‐order WENO‐Z scheme is proposed by analogy with the non‐normalized weights of the reformulated fifth‐order adaptive order (AO) WENO scheme. We show that if the original fifth‐order WENO‐AO scheme is rewritten as the… read more here.

Published in 2018 at "Journal of Scientific Computing"

DOI: 10.1007/s10915-017-0587-4

Abstract: In this paper, we develop an improved third-order WENO-Z scheme. Firstly, a new reference smoothness indicator is derived by slightly modifying that of WENO-N3 scheme proposed by Wu and Zhang (Int. J. Numer. Meth. Fl.… read more here.

Published in 2024 at "Physics of Fluids"

DOI: 10.1063/5.0216835

Abstract: In high-resolution numerical simulations of flows characterized by both multiscale turbulence and discontinuities, the conflict between spectral characteristics and stability becomes increasingly pronounced as the order of accuracy improves. To address this challenge, we proposed… read more here.

Published in 2025 at "Applications of Mathematics"

DOI: 10.21136/am.2025.0258-24

Abstract: A new fifth-order weighted essentially nonoscillatory (WENO) scheme is designed to approximate Hamilton-Jacobi equations. As employing a fifth-order linear approximation and three third-order ones on the same six-point stencil as before, a newly considered WENO-Z… read more here.

Published in 2024 at "Geoscientific Model Development"

DOI: 10.5194/gmd-17-6105-2024

Abstract: Abstract. Modelling magma transport requires robust numerical schemes for chemical advection. Current numerical schemes vary in their ability to be mass conservative, computationally efficient, and accurate. This study compares four of the most commonly used… read more here.
