Reactive multiphase flow

Challenges

Multiphase reactive processes occur in many chemical or biotechnological processes.  In order to model these processes, it is necessary to understand the complex interaction of the various influencing factors (material properties, operating parameters, apparatus geometry) on these processes and to be able to map them reliably.
We use various approaches for modelling these processes, including

  • Population balances to describe the properties of disperse phases
  • CFD for single and multiphase flows
  • Data-driven modelling approaches 

These methods are used to describe the following processes, among others:

  • Bubble size distributions in bubble columns and stirred tanks
  • Foam growth in gassed stirred tanks
  • Internal flows in jet loop reactors
  • Product yields in reaction mixing pumps.

Various measurement techniques are used to generate calibration/training or validation data, including
