Characterizing the Orientational and Network Dynamics of Polydisperse Nanofibres at the Nanoscale
Christophe Brouzet, Nitesh Mittal, Fredrik Lundell +1
Polydisperse fibre networks are the basis of many natural and man-made architectures, ranging from high-performance bio-based materials to components of living cells and tissues. T…
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…
Orientation and dynamics of stiff polymeric nanoparticles
Christophe Brouzet, Nitesh Mittal, L. Daniel Söderberg +1
Successful assembly of suspended nanoscale rod-like particles depends on fundamental phenomena controlling rotational and translational diffusion. Despite the significant developme…
Dynamic characterization of cellulose nanofibrils in sheared and extended semi-dilute dispersions
Tomas Rosén, Nitesh Mittal, Stephan V. Roth +3
New materials made through controlled assembly of dispersed cellulose nanofibrils (CNF) has the potential to develop into biobased competitors to some of the highest performing mat…
