We are pleased to announce that Wim-Paul Breugem from the TU Delft (The Netherlands), will give the SFB 1313 "Pretty Porous Science Lecture" #34. His talk will be on "Sedimentation characteristics and rheology of non-colloidal suspensions".
The talk will be a hybrid event. If you are interested in participating in the lecture online, please contact us via e-mail
Abstract
The study of suspension flows is relevant to many processes in nature and a wide variety of industrial applications. Examples are sediment transport in rivers, excavation and slurry transport in dredging, sedimentation in settling basins, fluidized beds in chemical industry, and 3D printing of, e.g., food, paper pulp and cement slurries.
In this talk I will present results from particle-resolved Direct Numerical Simulations (DNS) of non-colloidal particle suspensions for which Brownian motion and molecular forces such as Van der Waals and electrostatic forces can be neglected (i.e., particle diameters >> 1 micron). The first part of the presentation will be devoted to sedimentation in the inertial regime, while in the second part I will discuss the rheological behavior of neutrally-buoyant particle suspensions in a simple shear flow.
