Separation of platelets from other blood cells in continuous-flow by dielectrophoresis field-flow-fractionation

Philippe Renaud, Niccolo Piacentini, Raphaël Tornay

We present a microfluidic device capable of separating platelets from other blood cells in continuous flow using dielectrophoresis field-flow-fractionation. The use of hydrodynamic focusing in combination with the application of a dielectrophoretic force a ...

Influence of tributary widening on morphology and hydraulic variability in confluence zones

Anton Schleiss, Koen Blanckaert, Marcelo Leite Ribeiro

In the aim of assessing the potential of tributary widening with respect to river rehabilitation in fluvial systems, attention is focused on the effects of tributary widening on the morphodynamic processes of confluence zones. Systematic tests were perform ...

Reduced formulation of a steady fluid-structure interaction problem with parametric coupling

Gianluigi Rozza, Toni Mikael Lassila

We propose a two-fold approach to model reduction of fluid-structure interaction. The state equations for the fluid are solved with reduced basis methods. These are model reduction methods for parametric partial differential equations using well-chosen sna ...

Improving the accuracy of four-receiver acoustic Doppler velocimeter (ADV) measurements in turbulent boundary layer flows

Ulrich Lemmin, Fereshteh Bagherimiyab Hunkeler

Acoustic Doppler instrument measurements suffer from random spikes and Doppler noise. Using a four-receiver ADV (acoustic Doppler velocimeter; Vectrino manufactured by Nortek) that allows recording beam velocities, we combine a spike-removal procedure on t ...

A time-resolved dynamic stall investigation based on coherent structure analysis

Karen Ann J Mulleners

Dynamic stall on an airfoil comprises a series of complex aerodynamic phenomena in response to an unsteady change of the angle of attack. It is accompanied by a lift overshoot and delayed massive flow separation with respect to static stall. The classical ...

Unsteady flow in a channel with large scale bank roughness

Anton Schleiss, Tobias Meile

Systematic investigations on positive and negative surge waves from upstream have been conducted in a 40 m long channel with a mean bed slope of 1.14? and non-prismatic bank geometries. The channel banks included macro-roughness elements, namely various ca ...

Local hemodynamics and intimal hyperplasia at the venous side of a porcine arteriovenous shunt

Nikolaos Stergiopoulos

Venous anastomotic intimal hyperplasia (IH) observed in the arteriovenous shunt (AVS) has been associated with disturbed hemodynamics. This study aims to correlate hemodynamics with wall histology and wall mechanics by examining the flow field in AVS with ...

Reduction theory for symmetry breaking with applications to nematic systems

François Gay-Balmaz, Cesare Tronci

We formulate Euler-Poincare and Lagrange-Poincare equations for systems with broken symmetry. We specialize the general theory to present explicit equations of motion for nematic systems, ranging from single nematic molecules to biaxial liquid crystals. Th ...

Influence of macro-rough banks on steady flow in a channel

Anton Schleiss, Tobias Meile

High-head storage hydropower plants operate their turbines during periods of high energy demand. The starting and stopping of turbines results in rapid fluctuations of discharge and water levels in rivers called hydropeaking, which are unfavorable from an ...

Eliminating Turbulence in Spatially Intermittent Flows

Tobias Schneider

Flows through pipes and channels are the most common means to transport fluids in practical applications and equally occur in numerous natural systems. In general, the transfer of fluids is energetically far more efficient if the motion is smooth and lamin ...
