Maarten is a Reader in the Fluid Mechanics section in the department of Civil and Environmental Engineering at Imperial College. He has an MSc in Environmental Fluid Mechanics and a PhD in Applied Physics, both from Delft University of Technology. Apart from running an active research group, he teaches both at under- and postgraduate level.
Maarten's research interests comprise transport processes in fluids, generally involving wall-bounded turbulence and buoyancy effects. Application areas are transport processes in urban areas (urban heat island, dispersion, microclimate), atmospheric convection, building ventilation (stratified environments, plumes/jets, exchange flows), water quality in distribution systems (mass transfer), groundwater flows and oceanography. Areas of active research include:
- Air quality and urban microclimate in cities, particularly focused on sustainability. Here we use high-fidelity Large-Eddy Simulation (LES) and Urban Energy Balance models to quantify the impact of sustainable infrastructure like green roofs and green walls on air quality and the urban heat island effect.
- Turbulent entrainment in various guises (jets/plumes, volcanic ash, gravity currents, atmospheric/oceanic boundary layers etc). We use Direct Numerical Simulation and theory to get unprecedented insight into this important, yet notoriously difficult to measure, phenomenon.
- The behaviour of particles in turbulent flows. Applications to microplastics in the sea and cloud droplets.
Maarten leads a diverse group of excellent PhD students and post-docs with backgrounds ranging from Aeronautical, Civil and Mechanical Engineering, Mathematics and Physics. There are regular opportunities for PhD and post-doc positions. Please send me an E-mail if you are interested.
