Maarten is a Senior Lecturer 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 frum running an active research group, he is the year 1 coordinator for the MEng programme and 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:
- 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.
- Flows and air quality in cities, particularly focussed 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.
- The behaviour of cloud droplets and inertial particles near turbulent-nonturbulent interfaces (vacancy for two Early Stage Researchers as part of a European project - please send me an E-mail if interested).
