From the year 2011 to 2015, I was a joint PhD student in the Mathematics of Computational Science (MACS) group of Prof. J.J.W. van der Vegt and the Multi-Scale Mechanics (MSM) group of Prof. S. Luding at the University of Twente. I am a regular reviewer of journals such as Granular Matter and Computational Particle Mechanics. Besides reviewing, I am also a member of the J.M. Burgerscentrum Research School for Fluid Mechanics (JMBC), Graduate School of Engineering Mechanics (EM) and the American Physical Society (APS).
Multi-Scale Research Interests
Currently, my research focuses on the modelling of complex granular phenomena via developing novel numerical methods and utilising state-of-the-art experimental calibration and validation techniques.
Modelling granular systems is a multi-scale (multi-step) challenge requiring a blend of both experiments and simulations. Thereby, figure below illustrates a state-of-the-art framework showcasing such a blend.
Given this multi-scale nature of modelling granular materials, in the last years, I have gained immense knowledge relating to each step illustrated in the above framework. Hence, allowing me to deepen my understanding and, more importantly, make a few valuable contributions to the granular community.
Besides focusing on enriching the simulation methods for effectively predicting the granular phenomena, I have also indulged myself into the world of developing/utilising open-source easy-to-use simulation packages. Since 2013, I am a co-developer of a highly regarded open-source software suite, MercuryDPM – A fast, flexible and accurate particle solver. On the other hand, I also regularly utilise open-source continuum finite element method packages such as oomph-lib and hpGEM.
Past and Current Topics
Dense Granular Flows
- Modelling geophysical flows over inclined channels.
- Theoretical, experimental and numerical investigation of particle segregation mechanisms in inclined channel and rotating drum setups.
Micro-Macro Methods (MMM)
- Coarse Graining (CG): An accurate mapping technique for discrete particles to continuum fields.
- Coupled particle and fluid solver
In March 2018, MercuryLab will offer once again its popular courses on C++ programming and Discrete Particle Simulations. More information can be found here.
In September 2017, I have started working on modelling agglomeration processes (tabletting and selective laser sintering) of particulate materials. The agglomeratrion project will again utilise a multi-scale approach.
MercuryDPM is available here. New features: More complex shapes and Lees-Edwards boundaries; reorganisation of the file structure; and a better build system (cmake). Have fun with it, and, as always, give us your feedback!
