Numerical Simulation of Fluidization and Sedimentation Phenomena

Motivated by the direct numerical simulation of particulate flow (i.e., of the motion of fluid-particle mixtures) the authors of this paper, with the assistance of several collaborators, have introduced some years ago a computational methodology based on a fictitious domain formulation involving distributed Lagrange multipliers defined over the particles; this approach allows the flow computati...

Numerical simulation of a horizontal sedimentation tank considering sludge recirculation.

Most research conducted on the concentration distribution of sediment in the sedimentation tank does not consider the role of the suction dredge. To analyze concentration distribution more accurately, a suspended sediment transportation model was constructed and the velocity field in the sedimentation tank was determined based on the influence of the suction dredge. An application model was the...

Numerical Simulation of Quenching Process in Coal Gasification

This Master’s Thesis compares two computational fluid dynamics solvers: the commercial solver ANSYS CFX and the open source code OpenFOAM. Simple benchmark cases with compressible and incompressible flows are tested and compared. Thereafter the more complex process of quenching in coal gasification is simulated. This thesis work describes the simulation of a part of the coal gasification proces...

Numerical Simulation of Particle Segregation in a Bidisperse Suspension

Abstract: We have performed numerical simulations of a monolayer of a bidisperse suspension of colloidal particles in a cylindrical Couette flow taking into account hydrodynamic interactions (HI). We compare our simulation results with a simple phenomenological model and obtain good agreement for the monodisperse case. For a bidisperse suspension, we also obtain a good agreement if the ratio of...
