Cfd Simulations of Particle Laden Flows

This study presents the basic models for discrete and continuous particle laden flow simulation. An overview of the two main approaches, the Lagrangian discrete particle model and the Eulerian granular phase model is given. Moreover these two approaches are combined to a hybrid model to use the benefits of the discrete and continuous description. This safes computational time and increase the efficiency of particle laden flow simulations. Furthermore the models are extended to poly-disperse particles including a simple agglomeration model based on a population balance equation. Finally the usability of the models is shown at a pneumatic particle transport system including particle strand building and the separation of particles using an industrial cyclone.

Dr. David Schellander was born on 17th of December 1983 in Hall in Tirol in Austria. After his study of mechatronics he wrote his PhD-thesis at the Johannes Kepler University in Linz in the field of particle laden flow simulations. During his study he worked several years in the topic of particle flows and pneumatic particle laden flows. After finishing his PhD-thesis he used his expert knowledge in particle laden flow simulations to improve the quality of CFD simulation codes.
