Fluid Mechanics

The Fluid Mechanics Section (FM) at the Laboratory for Aero & Hydrodynamics performs research on the topics of turbulence and complex flows on an internationally competitive level. The research is carried out at a fundamental level using modern experimental and numerical methods and has a clear connection to processes in an applied or industrial context. Our research projects generally focus on four disciplines (or combinations hereof): Turbulence, Multiphase flow, Microfluidics and Biological flows. Examples of research within the turbulence program include: the generating of noise by jets, drag reduction by polymers and fibres, laminar-turbulent transition in pipe flow, scalar mixing and combustion. Within the multiphase program, recent research projects focus on demixing in three-phase flows, phase inversion, particle-fluid interaction, liquid-liquid Taylor-Couette flow, and gas/liquid transport with flow instabilities, liquid loading, and slugs in pipeline systems. The microfluidics program deals with the fundamentals and design of miniaturized process steps (such as mixing in a t-mixer, precipitation in a microchannel) and novel activation mechanisms, e.g. artificial cilia and activated surfaces. In 2006, the biological fluid mechanics program was started to apply the knowledge and tools from in particular microfluidics to biomedical applications. Recent achievements include the measurement inside an embryonic chicken heart and in vivo wall shear stress measurements in the vitelline network.
The programs are conducted in close collaboration with partners in academia (including participants in the J.M. Burgers center for fluid mechanics), industry, and governmental research institutes.
The research is performed with modern experimental and numerical methods. Experimental methods include particle image velocimetry and laser induced fluorescence; numerical methods include direct numerical simulation and large-eddy simulation.
