Particle Degradation during Vertical Transportation: Contribution of Abrasive Wear on Polymetallic Nodule Degradation

Manganese nodules have been lying on the deep sea soil for centuries before they became known. The first ones to discover the nodules were Murray and Renard, during their scientific cruise between 1872 and 1876 (Murray and Renard, 1876). The Clarion-Clipperton Zone, located between Mexico and Hawaii, appears to have a virtually inexhaustible...

CFD-DEM Coupling for Systems of Fluid and Non-Spherical Particles

The models for CFD-DEM coupling for fluid-particles simulations are explored. Emphasis is given to the implementation of a multisphere approach to handle non-spherical particles and to improvements of current features available in software packages. Some tests and applications are proposed.

Study of Rheological Behaviour of Spherocylindrical Particle Suspension via CFD-DEM: Formulation of Stress-Closure for Industrial Fluidized Bed Simulation

While colloidal suspensions of non-spherical particles have been studied relatively extensively, granular suspensions of non-spherical particles are rarely studied. The rheological behaviour of elongated granular particles is therefore not well known. This thesis deals with suspensions of rod-like particles of aspect ratio 4 subjected to shear...
