Finite-size spherical particles in a square duct flow of an elastoviscoplastic fluid: an experimental study
Sagar Zade, Tafadzwa John Shamu, Fredrik Lundell +1
The present experimental study addresses the flow of a Yield Stress Fluid with some elasticity (Carbopol gel) in a square duct. The behaviour of two fluids with lower and higher yi…
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 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…
