Aspect ratio effect on particle transport in turbulent duct flows
Azad Noorani, Ricardo Vinuesa, Luca Brandt +1
The dynamics of dilute micron-sized spherical inertial particles in turbulent duct flows is studied by means of direct numerical simulations of the carrier phase turbulence with on…
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…
Heat transfer in laminar Couette flow laden with rigid spherical particles
Mehdi Niazi Ardekani, Omid Abouali, Francesco Picano +1
We study heat transfer in plane Couette flow laden with rigid spherical particles by means of direct numerical simulations using a direct-forcing immersed boundary method to accoun…
Reduced particle settling speed in turbulence
Walter Fornari, Francesco Picano, Gaetano Sardina +1
We study the settling of finite-size rigid spheres in sustained homogeneous isotropic turbulence (HIT) by direct numerical simulations using an immersed boundary method to account…
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…
