Tomographic long-distance microPIV to investigate the small scales of turbulence in a jet at high Reynolds number
Daniele Fiscaletti, Daniele Ragni, Edwin F. J. Overmars +2
The small scales of turbulence in a high-Reynolds-number jet () are investigated with a \textmu PIV setup to overcome the optical limitations of conventional tomo…
The effect of finger spreading on drag of the hand in human swimming
Josje van Houwelingen, Dennis H. J. Willemsen, Rudie P. J. Kunnen +7
The effect of finger spreading on hydrodynamic drag in swimming is studied both with a numerical simulation and with laboratory experiments. Both approaches are based on the exact…
Advantage of a lead swimmer in drafting
J. Westerweel, K. Aslan, P. Pennings +1
We present results from model tests to investigate the effect of drafting in swimming, in particular for the lead swimmer. The drag for scaled-model passive swimmers was determined…
Collision model for fully-resolved simulations of flows laden with finite-size particles
Pedro Costa, Bendiks Jan Boersma, Jerry Westerweel +1
We present a collision model for particle-particle and particle-wall interactions in interface-resolved simulations of particle-laden flows. Three types of inter-particle interacti…
Experimental investigation of an oil droplet colliding with an oil-water interface
U. Miessner, E. Coyajee, R. Delfos +2
The impact of a buoyancy driven oil droplet with an oil-water interface is investigated using time-resolved Particle Image Velocimetry (PIV) along with a phase discrimination by me…
Influence of global rotation and Reynolds number on the large-scale features of a turbulent Taylor-Couette flow
Florent Ravelet, Rene Delfos, Jerry Westerweel
We experimentally study the turbulent flow between two coaxial and independently rotating cylinders. We determined the scaling of the torque with Reynolds numbers at various angula…
Comment on 'Critical behaviour in the relaminarization of localized turbulence in pipe flow'
Bjorn Hof, Jerry Westerweel, Tobias M. Schneider +1
This is a comment on arXiv:physics/0608292, subsequently published in Phys Rev Lett, 98, 014501 (2007), in which Willis and Kerswell study in direct numerical simulations the stati…
