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…
Quantification of Uncertainties in Turbulence Modeling: A Comparison of Physics-Based and Random Matrix Theoretic Approaches
Jian-Xun Wang, Rui Sun, Heng Xiao
Numerical models based on Reynolds-Averaged Navier-Stokes (RANS) equations are widely used in engineering turbulence modeling. However, the RANS predictions have large model-form u…
Sediment Micromechanics in Sheet Flows Induced by Asymmetric Waves: A CFD-DEM Study
Rui Sun, Heng Xiao
Understanding the sediment transport in oscillatory flows is essential to the investigation of the overall sediment budget for coastal regions. This overall budget is crucial for t…
SediFoam: A general-purpose, open-source CFD-DEM solver for particle-laden flow with emphasis on sediment transport
Rui Sun, Heng Xiao
With the growth of available computational resource, CFD-DEM (computational fluid dynamics-discrete element method) becomes an increasingly promising and feasible approach for the…
