Niklas Hidman

Postdoc at Fluid Dynamics

Niklas is a Doctoral student at the multiphase flow group within the division of fluid dynamics. His research aims to investigate the complex flow and transport phenomena occurring in bubbly flows. To this end, fully resolved Direct Numerical Simulations is employed.

The new insights developed from these simulations will be used to improve existing CFD closure models in the context of Eulerian-Eulerian two fluids models, used by academics and industry, and allow for more efficient design and operation of particular industrial devices such as bubble column reactors.
