Personal profile

Research profile

Wim-Paul Breugem is specialized in fluid mechanics. He does fundamental research on turbulence, multiphase flows, flows in porous media and rheology using computational fluid dynamics, with applications in process, energy, environmental and maritime engineering and often in close collaboration with industrial partners.

More specifically, Breugem’s expertise covers: wall-bounded turbulent flows, turbulent drag reduction, atmospheric flows, suspension flows, bubbly flows, break-up of liquid jets, droplet coalescence, continuum modelling for porous-media and multiphase flows, slender-jet modelling, linear hydrodynamic stability analysis, Direct Numerical Simulation, Immersed Boundary Methods for particle-laden flows, Level-Set and Volume-of-Fluid methods for flows laden with deformable bubbles or drops, high-performance computing.

Applications Breugem has been working on, relate to: prilling for production of fertilizer pellets, rheology of dense suspensions used for 3D (extrusion-based) printing, sedimentation and fluidization processes, turbulent sediment transport through pipelines related to dredging applications, turbulent bed erosion near hydraulic structures or in dredging applications, turbulent flows over porous/permeable walls, shark-skin riblet textures or compliant (visco-elastic) coatings in maritime applications, ship air lubriction, by-pass pigging in pipelines, micro-fluidic flows driven by artificial cilia, and interannual climate variability in the tropical Atlantic region.


Wim-Paul Breugem (1976) is Associate Professor within the Process & Energy department at TU Delft since 2014. His research is centered around the theme "Computational Fluids Engineering" with a focus on development and use of computational models and methods for studying fluid flows related to engineering applications. He has an MSc in Applied Physics from TU Delft (1994-2000). He did his PhD research on the influence of wall permeability on laminar and turbulent flows at the same university within the Laboratory for Aero & Hydrodynamics at Mechanical Engineering. In January 2005, he obtained his PhD cum laude. From 2005 till 2007 he worked as a postdoc at KNMI (the Dutch weather and climate institute) on coupled ocean/atmosphere patterns of interannual climate variability in the tropical Atlantic region. In 2008 he started as an Assistant Professor on turbulence and multiphase flows within the Process & Energy department at TU Delft, first in the Fluid Mechanics group and since 2016 in the Multiphase Systems group. He got a tenured position in 2013 and obtained the "ius promovendi" in 2018. Breugem is currently supervising 4 PhD students. Among other teaching activities, he has been teaching the MSc course 'Turbulence' from 2010-2015 and is teaching the MSc course 'Introduction to Multiphase Flows' since 2016.
