Particle laden flows are widely present in various natural and technical settings such as sediment transport in rivers or industrial waste slurry transportation. Under specific conditions, the hydrodynamic interaction between particles and fluid can give rise to various interesting structures and patterns. One example is the formation of dense ring-shaped particle agglomerations in formerly homogeneous suspensions in rotating cylinders known as banding phenomena. Recently we discovered that the banding phenomena also occurs in Taylor Couette flows and can lead to a complete separation of particles by size. Moreover, in pressure-driven square capillary flows a variety of characteristic radial particle patterns was observed for different particle volume fractions.

The project “Suspensions in Rotating and Pressure driven Flows” is carried out in cooperation with the KTH Stockholm, Uni Duisburg Essen and the BTU Cottbus. For the investigation of pressure driven square duct and channel flows a microscopic setup, able to handle flow geometries up to 1000mm, has been designed at the SLA. In addition, two Taylor Couette setups have been established facilitating corotating flows with cylinder sizes ranging from 12 mm to 300mm and gap sizes down to 1mm. To resolve the 3D particle velocities and concentrations measurements even at high particle volume fractions we developed measurement techniques based on Astigmatism Particle Tracking Velocimetry (APTV) allowing us to measure in suspensions of up to 20% solid volume fraction ( Brockmann et al., Experiments in Fluids 61 (2), 1-19, Brockmann, Hussong, Experiments in Fluids 62 (1), 1-11).
