Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Bedload transport of sediment mixtures is fundamental to river morphology and impacts aquatic ecology. Adding fine grains enhances coarse‐grain transport, yet controlling mechanisms remain elusive. Employing discrete element simulations, we examine how fine‐grain size and proportion influence coarse‐grain flux.

Strong Universality in Forced and Decaying Turbulence
, 2003 The weak version of universality in turbulence refers to the independence of the scaling exponents of the $n$th order strcuture functions from the statistics of the forcing.

International Journal for Numerical Methods in Engineering, Volume 127, Issue 7, 15 April 2026.ABSTRACT In this article, we propose a novel numerical framework for the non‐isothermal Cahn–Hilliard–Navier–Stokes two‐phase flow system, which couples the incompressible Navier–Stokes equations, the Cahn–Hilliard phase‐field equation, and the heat transport equation to capture temperature‐dependent two‐phase flow dynamics.

A Multi-Dimensional Virtual Characteristic Scheme for Laminar and Turbulent Incompressible Flows
Journal of Applied Fluid Mechanics, 2016 A multi-dimensional virtual characteristic-based scheme (MVCB) by the aid of artificial compressibility is developed for convective fluxes in laminar and turbulent incompressible flows. The proper combinations of compatibility equations are determined to

An experimental and computational investigation of the flow field about a transonic airfoil in supercritical flow with turbulent boundary-layer separation [PDF]
A combined experimental and computational research program is described for testing and guiding turbulence modeling within regions of separation induced by shock waves incident in turbulent boundary layers. Specifically, studies are made of the separated

Evaluation of a research circulation control airfoil using Navier-Stokes methods [PDF]
The compressible Reynolds time averaged Navier-Stokes equations were used to obtain solutions for flows about a two dimensional circulation control airfoil. The governing equations were written in conservation form for a body-fitted coordinate system and
