Particle Size Effects on Dynamic Behavior of Heated Spheroidal Particles in Shear Flow

Chemical Engineering &Technology, Volume 49, Issue 3, March 2026.
Understanding the dynamics of nonspherical particles in shear‐driven flows is essential for a wide range of engineering applications. This study examines how confinement ratio, thermal effects, and interparticle interactions influence the migration, equilibrium positions, and rotation of nonspherical particles in such flows.

Energetics of the Upper‐Ocean Under Sea Ice: Frictional Dissipation Versus Baroclinic Production

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract In polar regions, the presence of sea ice is known to reduce the ocean's eddy kinetic energy (EKE) by enhancing frictional dissipation at the surface. Here, using a coupled ocean—sea ice model, we discuss a mechanism that can instead increase EKE generation under sea ice and, in our simulations, compensates surface dissipation by 69% to 30 ...

Optimized Weighted Essentially Nonoscillatory Third-Order Schemes for Hyperbolic Conservation Laws

Journal of Applied Mathematics, 2013
We describe briefly how a third-order Weighted Essentially Nonoscillatory (WENO) scheme is derived by coupling a WENO spatial discretization scheme with a temporal integration scheme. The scheme is termed WENO3.

An Adaptive WENO Collocation Method for Differential Equations with Random Coefficients

Mathematics, 2016
The stochastic collocation method for solving differential equations with random inputs has gained lots of popularity in many applications, since such a scheme exhibits exponential convergence with smooth solutions in the random space.

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

Geoscience 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.

On the Stability Barrier of Hermite Type Discretizations of Advection Equations

Numerical 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

Journal 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.

A brief review on the convergence to steady state solutions of Euler equations with high-order WENO schemes

Advances in Aerodynamics, 2019
Weighted essentially non-oscillatory (WENO) schemes are a class of high-order shock capturing schemes which have been designed and applied to solve many fluid dynamics problems to study the detailed flow structures and their evolutions.
