From nearly homogeneous to core-peaking suspensions: insight in suspension pipe flows using MRI and DNS
Willian Hogendoorn, Wim-Paul Breugem, David Frank +3
Magnetic Resonance Imaging (MRI) experiments have been performed in conjunction with Direct Numerical Simulations (DNS) to study neutrally buoyant particle-laden pipe flows. The fl…
The effect of the Stokes boundary layer on the dynamics of particle pairs in an oscillatory flow
T. J. J. M. van Overveld, W. -P. Breugem, H. J. H. Clercx +1
The alignment of a pair of spherical particles perpendicular to a horizontally oscillating flow is attributed to a non-zero residual flow, known as steady streaming. This phenomeno…
A numerical study of a pair of spheres in an oscillating box filled with viscous fluid
T. J. J. M. van Overveld, M. T. Shajahan, W. -P. Breugem +2
When two spherical particles submerged in a viscous fluid are subjected to an oscillatory flow, they align themselves perpendicular to the direction of the flow leaving a small gap…
Oscillatory laminar shear flow over a compliant viscoelastic layer on a rigid base
H. O. G. Benschop, W. -P. Breugem
We present an analytical study of oscillatory laminar shear flow over a compliant viscoelastic layer on a rigid base. This problem relates to oscillating blood flow in viscoelastic…
Drag Reduction by Herringbone Riblet Texture in Direct Numerical Simulations of Turbulent Channel Flow
H. O. G. Benschop, W. P. Breugem
A bird-feather-inspired herringbone riblet texture was investigated for turbulent drag reduction. The texture consists of blade riblets in a converging/diverging or herringbone pat…
Effects of the finite particle size in turbulent wall-bounded flows of dense suspensions
Pedro Costa, Francesco Picano, Luca Brandt +1
We use interface-resolved simulations to study finite-size effects in turbulent channel flow of neutrally-buoyant spheres. Two cases with particle sizes differing by a factor of 2,…
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…
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…
Channel flow of rigid sphere suspensions: particle dynamics in the inertial regime
Iman Lashgari, Francesco Picano, Wim Paul Breugem +1
We consider suspensions of neutrally-buoyant finite-size rigid spherical particles in channel flow and investigate the relation between the particle dynamics and the mean bulk beha…
Turbulent channel flow of dense suspensions of neutrally-buoyant spheres
F. Picano, W. -P. Breugem, L. Brandt
Dense particle suspensions are widely encountered in many applications and in environmental flows. While many previous studies investigate their rheological properties in laminar f…
Laminar, turbulent and inertial shear-thickening regimes in channel flow of neutrally buoyant particle suspensions
Iman Lashgari, Francesco Picano, Wim-Paul Breugem +1
The aim of this Letter is to characterize the flow regimes of suspensions of finite-size rigid particles in a viscous fluid at finite inertia. We explore the system behavior as fun…
Shear thickening in non-Brownian suspensions: an excluded volume effect
Francesco Picano, Wim-Paul Breugem, Dhrubaditya Mitra +1
Shear thickening appears as an increase of the viscosity of a dense suspension with the shear rate, sometimes sudden and violent at high volume fraction. Its origin for noncolloida…
