A comparison between the FENE-P and sPTT constitutive models in Large Amplitude Oscillatory Shear (LAOS)
Thomas P John, Robert J Poole, Adam Kowalski +1
The FENE-P and sPTT viscoelastic models are widely used for modelling of complex fluids. Although they are derived from distinct micro-structural theories, these models can become…
Perspectives on viscoelastic flow instabilities and elastic turbulence
Sujit S. Datta, Arezoo M. Ardekani, Paulo E. Arratia +20
Viscoelastic fluids are a common subclass of rheologically complex materials that are encountered in diverse fields from biology to polymer processing. Often the flows of viscoelas…
Creeping thermocapillary motion of a Newtonian droplet suspended in a viscoelastic fluid
Paolo Capobianchi, Mahdi Davoodi, Robert J. Poole +3
In this work we consider theoretically the problem of a Newtonian droplet moving in an otherwise quiescent infinite viscoelastic fluid under the influence of an externally applied…
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,…
Secondary flows of viscoelastic fluids in serpentine microchannels
Lucie Ducloue, Laura Casanellas, Simon J. Haward +5
Secondary flows are ubiquitous in channel flows, where small velocity components perpendicular to the main velocity appear due to the complexity of the channel geometry and/or that…
Bundling of elastic filaments induced by hydrodynamic interactions
Yi Man, William Page, Robert J. Poole +1
Peritrichous bacteria swim in viscous fluids by rotating multiple helical flagellar filaments. As the bacterium swims forward, all its flagella rotate in synchrony behind the cell…
Enhanced Microfluidic Mixing via a Tricritical Spiral Vortex Instability
Simon J. Haward, Robert J. Poole, Manuel A. Alves +3
Experimental measurements and numerical simulations are made on fluid flow through cross-slot devices with a range of aspect (depth:width) ratios, 0.4 < alpha < 3.87. For low Reyno…
Serpentine channels: micro -- rheometers for fluid relaxation times
Josephine Zilz, Christof Schäfer, Christian Wagner +3
We propose a novel device capable of measuring the relaxation time of viscoelastic fluids as small as 1\,ms. In contrast to most rheometers, which by their very nature are concerne…
Geometric scaling of purely-elastic flow instabilities
J. Zilz, R. J. Poole, M. A. Alves +3
We present a combined experimental, numerical and theoretical investigation of the geometric scaling of the onset of a purely-elastic flow instability in a serpentine channel. Good…
