Turbulent emulsification is of huge industrial relevance for food processing. High-pressure homogenizers and rotor-stators capable of creating these products have been available for a century, but they come with a high energy cost.

We argue that an understanding of turbulent drop breakup is essential for designing more efficient processes and to achieve this we must look beyond the techniques typically employed in food science. This webinar presents an overview of our group’s work on using direct numerical simulation with highly resoled interface tracking (together with some more traditional experimental techniques) to study how drops break in homogenizers, and discusses implications for process optimization.


Andreas Håkansson, Associate Professor, Lund University

Andreas Håkansson holds a PhD in Food Technology and is an Associate Professor in Food Engineering at Lund University, Sweden. He has 15 years' experience on conducting research on high-pressure homogenizers and rotor-stator mixers, using a combination of numerical approaches (computational fluid dynamics, CFD; large eddy simulation, LES; direct numerical simulation, DNS; population balance modelling, PBM) as well as experimental techniques (particle image velocimetry, PIV; high-speed drop breakup experiments; traditional emulsification experiments).
