Valveless pumping at low Reynolds numbers
Amselem Gabriel, Clanet Christophe, Benzaquen Michael
Pumping at low Reynolds number is a ubiquitously encountered feature, both in biological organisms and engineered devices. Generating net flow requires the presence of an asymmetry…
Hysteretic wave drag in shallow water
GP Benham, R Bendimerad, M Benzaquen +1
During motion from deep to shallow water, multiple equilibria may emerge, each with identical drag - a phenomenon that can be explained by a localised amplification of the wave dra…
Brachistochrone on a Velodrome
GP Benham, C Cohen, E Brunet +1
The Brachistochrone problem, which describes the curve that carries a particle under gravity in a vertical plane from one height to another in the shortest time, is one of the most…
Wave drag on asymmetric bodies
GP Benham, JP Boucher, R Labbe +2
An asymmetric body with a sharp leading edge and a rounded trailing edge produces a smaller wave disturbance moving forwards than backwards, and this is reflected in the wave drag…
Thin or bulky: optimal aspect ratios for ship hulls
Jean-Philippe Boucher, Romain Labbé, Christophe Clanet +1
Empirical data reveals a broad variety of hull shapes among the different ship categories. We present a minimal theoretical approach to address the problem of ship hull optimisatio…
Wicking in a powder
Pascal S. Raux, Héloise Cockenpot, Marco Ramaioli +2
We investigate the wicking in granular media by considering layers of grains at the surface of a liquid, and discuss the critical contact angle below which spontaneous impregnation…
