Grain-scale computations of barchan dunes
Nicolao Cerqueira Lima, Willian Righi Assis, Carlos Azael Alvarez +1
Barchans are crescent-shaped dunes commonly found in diverse environments and scales: from the 10-cm-long barchans found under water to the 1-km-long barchans on Mars, passing by t…
Contacts, motion and chain-breaking in a two-dimensional granular system displaced by an intruder
Douglas Daniel de Carvalho, Nicolao Cerqueira Lima, Erick de Moraes Franklin
We investigate numerically how the motion of an intruder within a two-dimensional granular system affects its structure and produces drag on the intruder. We made use of discrete n…
Resolved CFD-DEM simulations of the hydraulic conveying of coarse grains through a very-narrow elbow
Elmar Anton Schnorr Filho, Nicolao Cerqueira Lima, Erick de Moraes Franklin
This paper investigates numerically the hydraulic conveying of solids through a 90 elbow that changes the flow direction from horizontal to vertical, in the very-narrow c…
Motion and clustering of bonded particles in narrow solid-liquid fluidized beds
Fernando David Cúñez, Nicolao Cerqueira Lima, Erick de Moraes Franklin
This paper presents an experimental and numerical investigation of solid-liquid fluidized beds consisting of bonded spheres in very narrow tubes, i.e., when the ratio between the t…
