Nearly Complete Segregation of Submerged Grains in a Rotating Drum
Yu Chen, Deheng Wei, Si Suo +2
Density-driven segregations, extensively studied in a simple rotating drum, are enriched with a wide range of underlying physics. Diverse symmetrical segregation patterns formed by…
On the Drag Coefficient Universality of a Rough Grain in Creeping Flow
Si Suo, Deheng Wei, Budi Zhao +2
Controversy exists regarding whether grain morphology reduces or enhances the drag of a single grain in creeping flows; further complication occurs when orientation dependence for…
Drag coefficient for irregularly shaped grains: rotational dependence at high Reynolds numbers
Álvaro Vergara, Deheng Wei, Raúl Fuentes
The nature and behaviour of the drag coefficient of irregularly shaped grains within a wide range of Reynolds numbers is discussed. Using computational fluid dynamics (CFD) tools,…
Contact behaviour of simulated rough spheres generated with spherical harmonics
Deheng Wei, Chongpu Zhai, Dorian A. H. Hanaor +1
Normal contact behaviour between non adhesive fractal rough particles is studied using a finite element method (FEM). A series of spherical grain surfaces with distinguished roughn…
