Turbulent channel flow of a dense binary mixture of rigid particles
Iman Lashgari, Francesco Picano, Pedro Costa +2
We study turbulent channel flow of a binary mixture of finite-size neutrally-buoyant rigid particles by means of interface-resolved direct numerical simulations. We fix the bulk Re…
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…
Drag reduction in turbulent channel flow laden with finite-size oblate spheroids
M. Niazi Ardekani, P. Costa, W. -P. Breugem +2
We study suspensions of oblate rigid particles in a viscous fluid for different values of the particle volume fractions. Direct numerical simulations have been performed using a di…
Numerical Study of the Sedimentation of Spheroidal Particles
Mehdi Niazi Ardekani, Pedro Costa, Wim-Paul Breugem +1
The gravity-driven motion of rigid particles in a viscous fluid is relevant in many natural and industrial processes, yet this has mainly been investigated for spherical particles.…
Universal Scaling Laws for Dense Particle Suspensions in Turbulent Wall-Bounded Flows
Pedro Costa, Francesco Picano, Luca Brandt +1
The macroscopic behavior of dense suspensions of neutrally-buoyant spheres in turbulent plane channel flow is examined. We show that particles larger than the smallest turbulence s…
