RANS Equations with Explicit Data-Driven Reynolds Stress Closure Can Be Ill-Conditioned
Jin-Long Wu, Heng Xiao, Rui Sun +1
Reynolds-averaged Navier--Stokes (RANS) simulations with turbulence closure models continue to play important roles in industrial flow simulations. However, the commonly used linea…
Study of sedimentation of non-cohesive particles via CFD-DEM simulations
Shan-Lin Xu, Rui Sun, Yuan-Qiang Cai +1
The sedimentation process of granular materials exists ubiquitously in nature and many fields which involve the solid-liquid separation. This paper employs the coupled computationa…
Representation of Reynolds Stress Perturbations with Application in Machine-Learning-Assisted Turbulence Modeling
Jinlong Wu, Rui Sun, Sylvain Laizet +1
Numerical simulations based on Reynolds-Averaged Navier--Stokes (RANS) equations are widely used in engineering design and analysis involving turbulent flows. However, RANS simulat…
Investigating the Settling Dynamics of Cohesive Silt Particles With Particle-Resolving Simulations
Rui Sun, Heng Xiao, Honglei Sun
The settling of cohesive sediment is ubiquitous in aquatic environments. In the settling process, the silt particles show behaviors that are different from non-cohesive particles d…
Particle dynamics in self-generated dunes over a range of hydraulic and sediment transport conditions using LES--DEM
Rui Sun, Heng Xiao, Kyle Strom
Direct measurement of vertical and longitudinal sediment fluxes on migrating sandy bedforms are extremely difficult to perform in both the field and laboratory. In this study we us…
Realistic Representation of Grain Shapes in CFD--DEM Simulations of Sediment Transport: A Bonded-Sphere Approach
Rui Sun, Heng Xiao
Development of algorithms and growth of computational resources in the past decades have enabled simulations of sediment transport processes with unprecedented fidelities. The Comp…
