Geert Brethouwer

Geert Brethouwer is a Researcher at KTH Royal Institute of Technology, working within the FLOW MECHANICS group. He focuses on fluid mechanics, turbulence, and computational fluid dynamics, with expertise in reactive flows, atmospheric boundary layers, and large-eddy simulation (LES) modeling. His research emphasizes turbulence modeling, scalar transport in complex flows, and the effects of rotation, stratification, and roughness on flow dynamics.

He contributes to courses such as Technical Fluid Mechanics (SG1220) and Thermodynamics (SG1216) as a teaching assistant, reflecting his commitment to both research and education in engineering sciences. His work integrates advanced numerical methods like DNS and LES to study transitional and turbulent flows, with applications in environmental fluid mechanics and combustion physics.

Key research interests include Reynolds-stress modeling for stratified flows, passive scalar transport in rotating systems, and improving LES accuracy through subgrid-scale closures. His studies often address anisotropic turbulence, boundary layer transitions, and the interplay between flow instabilities and scalar mixing processes.

Brethouwer’s publications span over two decades, with recent work focusing on heat/mass transfer disparities in rotating systems, turbulent combustion physics, and the explicit algebraic modeling of atmospheric boundary layers. He actively engages with computational tools like OpenFOAM to enhance LES fidelity while minimizing numerical dissipation.

His research group collaborates on projects involving wall-jet flows, particle-laden turbulent flows, and the statistical analysis of high-order velocity fluctuations. Despite no awards explicitly listed in the provided texts, his extensive publication record underscores significant contributions to fluid dynamics methodologies.
