The lecture topic:Multiscale simulations of agitated solid-liquid suspensions

The presenter:  Jos Derksen

Brief introduction of the presenter:

Jos  was educated in the Netherlands where he obtained a PhD degree in  Applied Physics from Eindhoven University of Technology in 1991. In  2007, he moved to the University of Alberta, Canada. In 2013, he came  back to Europe to work with the University of Aberdeen (UK) and in  2014/2015 Delft University.His research focuses on highly resolved  simulations of multiphase flow and transport processes.

Content of the lecture:

Suspending  solids in liquid through agitation is a feature of many processes. As  is true for many multiphase systems, solids suspension is multi-scale in  nature. The behaviour of submillimeter particles is controlled by the  flow generated by a thousand times larger impeller. Vice versa, the  particles make themselves collectively feel at larger length scale by  impacting the rheology of the solids-liquid mixture. Getting this length  (and time) scale interaction right is a challenge for modelling and  simulation approaches. By using simulations to understand the details at  small scale one can try and build closure models that properly account  for the way micro-scale phenomena impact the macro scale. The  presentation will focus on examples rather than methodology to  illustrate the subject of scale interaction as sketched above.
