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 (…
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…
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…
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…
