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...
