On the fully coupled dynamics of flexible fibres dispersed in modulated turbulence
Stefano Olivieri, Andrea Mazzino, Marco E. Rosti
The present work investigates the mechanical behaviour of finite-size, elastic and inertial fibres freely moving in a homogeneous and isotropic turbulent flow at moderate Reynolds…
A fast and efficient tool to study the rheology of dense suspensions
Alessandro Monti, Vikram Rathee, Amy Q. Shen +1
A cutting-edge software is presented to tackle the Newton-Euler equations governing the dynamics of granular flows and dense suspensions in Newtonian fluids. In particular, we prop…
Modulation of homogeneous and isotropic turbulence in emulsions
Marco Crialesi-Esposito, Marco Edoardo Rosti, Sergio Chibbaro +1
We present a numerical study of emulsions in homogeneous and isotropic turbulence at . The problem is addressed via Direct Numerical Simulations (DNS), where the Volume o…
Shear-thinning and shear-thickening emulsions in shear flows
Marco Edoardo Rosti, Shu Takagi
We study the rheology of a two-fluid emulsion in semi-concentrated conditions; the solute is Newtonian while the solvent an inelastic power law fluid. The problem at hand is tackle…
Puff turbulence in the limit of strong buoyancy
Andrea Mazzino, Marco Edoardo Rosti
We provide a numerical validation of a recently proposed phenomenological theory to characterize the space-time statistical properties of a turbulent puff, both in terms of bulk pr…
The effect of droplet coalescence on drag in turbulent channel flows
Ianto Cannon, Daulet Izbassarov, Outi Tammisola +2
We study the effect of droplet coalescence on turbulent wall-bounded flows, by means of direct numerical simulations. In particular, the volume-of-fluid and front-tracking methods…
Unraveling the secrets of turbulence in a fluid puff
Andrea Mazzino, Marco E Rosti
Turbulent puffs are ubiquitous in everyday life phenomena. Understanding their dynamics is important in a variety of situations ranging from industrial processes to pure and applie…
Universal flapping states of elastic fibers in modulated turbulence
Stefano Olivieri, Andrea Mazzino, Marco E. Rosti
We study the fully-coupled dynamics between a fully-developed turbulent flow and an ensemble of immersed flexible fibers. We vary the concentration of the suspension, the mechanica…
A fully Eulerian hybrid Immersed Boundary-Phase Field Model for contact line dynamics on complex geometries
Armin Shahmardi, Marco Edoardo Rosti, Outi Tammisola +1
We present a fully Eulerian hybrid immersed-boundary/phase-field model to simulate wetting and contact line motion over any arbitrary geometry. The solid wall is described with a v…
Stagnation points control chaotic fluctuations in viscoelastic porous media flow
Simon J. Haward, Cameron C. Hopkins, Amy Q. Shen
Viscoelastic flows through porous media become unstable and chaotic beyond critical flow conditions, impacting industrial and biological processes. Recently, Walkama \textit{et al.…
Near-wall turbulence alteration with the Transpiration-Resistance Model
Seyed Morteza Habibi Khorasani, Uǧis Lācis, Simon Pasche +2
A set of boundary conditions called the Transpiration-Resistance Model (TRM) are investigated in altering near-wall turbulence. The TRM has been previously proposed by \citet{Lacis…
Microtomographic PIV measurements of viscoelastic instabilities in a 3D micro-contraction
Daniel W. Carlson, Amy Q. Shen, Simon J. Haward
Viscoelastic flow through an abrupt planar contraction geometry above a certain Weissenberg number (Wi) is well known to become unstable upstream of the contraction plane via a cen…
Finite-size evaporating droplets in weakly compressible homogeneous shear turbulence
Nicolò Scapin, Federico Dalla Barba, Giandomenico Lupo +3
We perform interface-resolved simulations of finite-size evaporating droplets in weakly-compressible homogeneous shear turbulence (HST). The study is conducted by varying three dim…
Direct numerical simulation of flapping flags in grid-induced turbulence
Stefano Olivieri, Francesco Viola, Andrea Mazzino +1
A fully-resolved direct-numerical-simulation (DNS) approach for investigating flexible bodies forced by a turbulent incoming flow is designed to study the flapping motion of a flex…
Asymptotic turbulent friction in 2D rough-walled flows
Alexandre Vilquin, Julie Jagielka, Simeon Djambov +6
The friction f is the property of wall-bounded flows that sets the pumping cost of a pipeline, the draining capacity of a river, and other variables of practical relevance. For hig…
