During my postdoc at the University of Rochester, working with Dr. Rachel Glade, I performed numerical simulations using CFD-DEM models to investigate the role of particle shape on the granular segregation that happens in most industrial and geophysical applications. A groundbreaking study that we developed at UofR, revealed how even small difference in particles' shape may induce drastic changes in the level of segregation, having direct impacts to predict geohazards (video in the right) and preventing segregation in industry (video below).
After revealing the importance of particles shape in sediment transport, we also tackled this problem by understanding particle-particle interactions and fluid-particle interactions for dry and wet cases of study.
We do know that the network of force chains inside a granular bed is very important to predict the rheology of the grains. Therefore, we are projecting to make some experiments involving photoelastic particles with different shapes. STAY TUNNED for upcoming projects.
