Multiphase flows research group

The most straightforward classification of multiphase flows is according to the state of different phases or components and, therefore, one may refer to gas-solid, liquid-solid, liquid-liquid or gas-liquid flows. Alternatively, one uses terms such as gas-particle flows, bubbly flows etc.

Understanding multiphase flows includes dealing with a wide spectrum of spatial and temporal scales, working within a broad range of engineering disciplines and using a multitude of different modelling and computational approaches. Challenges arise from complex interactions of many flow patterns and entities (e.g. bubbles, drops, or solid particles) suspended in a fluid, but also from phenomena such as a possible change of phase within a system (typically present in gas-liquid systems), turbulence etc.

What we do

We specialize in advanced modeling and numerical simulations of a great range of fundamental and industrially relevant problems in the field of multiphase flows. The problems comprise all types of multiphase flows and involve techniques such as multiphase Direct Numerical Simulations, Lattice Boltzmann framework, Eulerian-Eulerian and Eulerian-Lagrangian simulations.

Some of the examples of our recent work will be given below. The cases involve applications such as chemical reactors (bubble columns), energy converters (fluidized beds, batteries), heat exchangers, falling film evaporators, bioscale reactors, devices in the food industry, crystallizers and design of advanced surfaces.

The group consists of typically 15 senior researchers, post-doctoral researchers and doctoral students. Listed below are the senior researchers.
