Free-stream preserving linear-upwind and WENO schemes on curvilinear grids [PDF]

open access: yesJournal of Computational Physics, 2018
Applying high-order finite-difference schemes, like the extensively used linear-upwind or WENO schemes, to curvilinear grids can be problematic. The geometrically induced error from grid Jacobian and metrics evaluation can pollute the flow field, and ...

A Data Library of Liquid Clouds Modelled With a Large Eddy Simulation Framework

open access: yesGeoscience Data Journal, Volume 13, Issue 1, January 2026.
Clouds from four global liquid cloud testbed regions are modelled using atmospheric large eddy simulations coupled to a detailed scheme for cloud microphysics, offering data suitable for examining interactions among cloud, aerosol and turbulence in warm, boundary‐layer clouds and for developing parameterizations for coarser‐scale models.

Well-balanced High-order Finite Difference Weighted Essentially Nonoscillatory Schemes for a First-order Z4 Formulation of the Einstein Field Equations

open access: yesThe Astrophysical Journal Supplement Series
We develop a new class of high-order accurate well-balanced finite difference (FD) weighted essentially nonoscillatory (WENO) methods for numerical general relativity (GR), which can be applied to any first-order reduction of the Einstein field equations,

On the Stability Barrier of Hermite Type Discretizations of Advection Equations

open access: yesNumerical Methods for Partial Differential Equations, Volume 42, Issue 1, January 2026.
ABSTRACT We establish a stability barrier for a class of high‐order Hermite‐type discretization of 1D advection equations underlying the hybrid‐variable (HV) and active flux (AF) methods. These methods approximate both cell averages and nodal solutions and evolve them in time simultaneously.

A Direct Assessment of Langmuir Turbulence Parameterizations in Idealized Coastal Merging Boundary Layers

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 1, January 2026.
Abstract Langmuir turbulence affects turbulent mixing in the ocean boundary layers and its effects require parameterizations in ocean circulation models. Most existing Langmuir turbulence parameterizations focus on the surface boundary layer in open oceans.

Hybrid WENO schemes for polydisperse sedimentation models

open access: yesInternational Journal of Computer Mathematics, 2015
Polydisperse sedimentation models can be described by a strongly coupled system of conservation laws for the concentration of each species of solids. Typical solutions for the sedimentation model considered for batch settling in a column include stationary kinematic shocks separating layers of sediment of different composition.

Implicit finite volume WENO schemes for solving hyperbolic conservation laws [PDF]

open access: yes, 2019
In this dissertation, we consider high order accurate, implicit, finite volume, weighted essentially non-oscillatoy (WENO) schemes for solving advection-diffusion equations.

High order weighted essentially non-oscillatory WENO-ZN schemes for hyperbolic conservation laws

open access: yes, 2022
In Shen et al. (2020), the authors have proposed a novel weighting method to construct the fifth-order WENO-ZN scheme to improve the accuracy at the second-order critical point.

A Two-Step High-Order Compact Corrected WENO Scheme

open access: yesAlgorithms
In this study, we introduce a novel 2-step compact scheme-based high-order correction method for computational fluid dynamics (CFD). Unlike traditional single-formula-based schemes, our proposed approach refines flux function values by leveraging results
