Turbulence modulation by finite-size spherical particles in Newtonian and viscoelastic fluids
Sagar Zade, Fredrik Lundell, Luca Brandt
We experimentally investigate the influence of finite-size spherical particles in turbulent flows of a Newtonian and a drag reducing viscoelastic fluid at varying particle volume f…
Buoyant finite-size particles in turbulent duct flow
Sagar Zade, Walter Fornari, Fredrik Lundell +1
Particle Image Velocimetry (PIV) and Particle Tracking Velocimetry (PTV) have been employed to investigate the dynamics of finite-size spherical particles, slightly heavier than th…
Turbulent channel flow of finite-size spherical particles with viscous hyper-elastic walls
M. N. Ardekani, M. E. Rosti, L. Brandt
We study single-phase and particulate turbulent channel flows, bounded by two incompressible hyper-elastic walls. Different wall elasticities are considered with and without a 10%…
Hemorheology in dilute, semi-dilute and dense suspensions of red blood cells
Naoki Takeishi, Marco E. Rosti, Yohsuke Imai +2
We present a numerical analysis of the rheology of a suspension of red blood cells (RBCs) in a wall-bounded shear flow. The flow is assumed as almost inertialess. The suspension of…
Turbulent duct flow with polymers
Armin Shahmardi, Sagar Zade, Mehdi N. Ardekani +4
We have performed direct numerical simulation of the turbulent flow of a polymer solution in a square duct, with the FENE-P model used to simulate the presence of polymers. First,…
Experimental investigation of turbulent suspensions of spherical particles in a square duct
Sagar Zade, Pedro Costa, Walter Fornari +2
We report experimental observations of turbulent flow with spherical particles in a square duct. Three particle sizes namely: = 40, 16 and 9 ( being the duct full he…
