Coherent structures in Newtonian and viscoelastic turbulent planar jets
Christian Amor, Adrián Corrochano, Giovanni Soligo +2
The addition of a small amount of long-chain polymers confers viscoelastic properties to Newtonian flows. The resulting non-Newtonian solution now exhibits different dynamics, such…
The broken link between space and time in elastic turbulence
Giulio Foggi Rota, Rahul K. Singh, Alessandro Chiarini +4
Elastic turbulence (ET), observed in flows of sufficiently elastic polymer solution at small inertia, is characterized by chaotic motions and power-law scaling of energy spectrum (…
2.5D turbulence in shear-thinning jets
Christian Amor, Giovanni Soligo, Andrea Mazzino +1
The dimensional transition in turbulent jets of a shear-thinning fluid is studied via direct numerical simulations. Our findings reveal that under vertical confinement, the flow ex…
Laminar planar jets of elastoviscoplastic fluids
Giovanni Soligo, Marco Edoardo Rosti
We perform numerical simulations of planar jets of elastoviscoplastic (EVP) fluid (\citet{saramito2007new} model) at low Reynolds number. Three different configurations are conside…
Effect of surfactant-laden droplets on turbulent flow topology
Giovanni Soligo, Alessio Roccon, Alfredo Soldati
In this work, we investigate flow topology modifications produced by a swarm of large surfactant-laden droplets released in a turbulent channel flow. Droplets have same density and…
Influence of density and viscosity on deformation, breakage, and coalescence of bubbles in turbulence
Francesca Mangani, Giovanni Soligo, Alessio Roccon +1
We investigate the effect of density and viscosity differences on a swarm of large and deformable bubbles dispersed in a turbulent channel flow. For a given shear Reynolds number,…
Morphology of clean and surfactant-laden droplets in homogeneous isotropic turbulence
Ianto Cannon, Giovanni Soligo, Marco E. Rosti
We perform direct numerical simulations of surfactant-laden droplets in homogeneous isotropic turbulence with Taylor Reynolds number of 180. The droplets are modelled using the vol…
Non-Newtonian turbulent jets at low-Reynolds number
Giovanni Soligo, Marco Edoardo Rosti
We perform direct numerical simulations of planar jets of non-Newtonian fluids at low Reynolds number, in typical laminar conditions for a Newtonian fluid. We select three differen…
