Discrete Particle Simulation and an Averaging Method of Particulate Flows
Dr. Haiping Zhu, School of Computing, Engineering and Mathematics, Western Sydney University
Particulate flows are quite common in nature and in industry. Their dynamic behaviour is very complicated due to the complex interactions between individual particles and their interactions with surrounding gas or liquid and wall. Understanding the microscopic mechanism in terms of these interactions is therefore the key leading to truly interdisciplinary research and producing results that can be generally used. This aim can be effectively achieved via particle scale research. An important discrete model is the so-called discrete element method. This technique can provide dynamic information, such as the trajectories of and transient forces acting on individual particles, which is difficult, if not impossible, to obtain by the conventional experimental techniques. Consequently, it has been increasingly used to study various particle flows. This presentation will provide a brief introduction to the discrete element method and an averaging method to link it to the continuum approach being widely used to describe the particulate systems at a macroscopic scale.
Dr Haiping Zhu is an Associate Professor in the School of Computing, Engineering and Mathematics at Western Sydney University (WSU). He joined WSU as a Senior Lecturer in 2009. Previously, he was a Research Fellow at the Laboratory for Simulation and Modelling of Particulate Systems in the School of Materials Science and Engineering at the University of New South Wales. From 1995 to 2001, Dr Zhu was a Lecturer and then an Associate Professor with the Department of Mechanics and Engineering Science at Peking University in China. He received his PhD degree in Dynamics of Mechanical Systems from Beijing Institute of Technology in 1995.
Dr Zhu has been devoted to the study of particulate systems, mechanical systems and related processes and has made various contributions in both the fundamental and applied aspects of these fields. He has published over 120 referred journal and conference papers and attracted a number of national competitive research grants. His current specific research areas/interests include granular dynamics, powder/particle technology, particle-structure-property relations, processing and handling of bulk/particulate materials, multi-scale simulation of particulate systems, modelling of particulate and multiphase processes, solids flow and segregation, fluid flow, heat and mass transfer in packed and fluidised beds, and dynamics of bridge structures.
