- Date From 12th April 2022
- Date To 12th April 2022

- Location Online. 12:00 BST. Duration 1 hour.
Suspending solids in liquid through agitation is a feature of many processes. Examples are crystallisation, dissolution and waste water treatment. 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. It also is an opportunity. 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.
Jos Derksen, Professor, University of Aberdeen
Jos was educated in the Netherlands where he obtained a PhD degree in Applied Physics from Eindhoven University of Technology in 1991.
After a short period with the Dutch Aerospace Laboratory (NLR), he joined Delft University of Technology in 1992. 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.
