Rheology of active polar emulsions: from linear to unidirectional and unviscid flow, and intermittent viscosity
Giuseppe Negro, Livio Nicola Carenza, Antonio Lamura +2
The rheological behaviour of an emulsion made of an active polar component and an isotropic passive fluid is studied by lattice Boltzmann methods. Different flow regimes are found…
Dynamically asymmetric and bicontinuous morphologies in active emulsions
Livio Nicola Carenza, Giuseppe Gonnella, Antonio Lamura +1
The morphology of a mixture made of a polar active gel immersed in an isotropic passive fluid is studied numerically. Lattice Boltzmann method is adopted to solve the Navier-Stokes…
Lattice Boltzmann Methods and Active Fluids
Livio Nicola Carenza, Giuseppe Gonnella, Antonio Lamura +2
We review the state of the art of active fluids with particular attention to hydrodynamic continuous models and to the use of Lattice Boltzmann Methods (LBM) in this field. We pres…
Comparison between isothermal collision-streaming and finite-difference lattice Boltzmann models
Giuseppe Negro, Sergiu Busuioc, Victor E. Ambrus +3
We present here a comparison between collision-streaming and finite-difference lattice Boltzmann (LB) models. This study provides a derivation of useful formulae which help one to…
Morphology and flow patterns in highly asymmetric active emulsions
Giuseppe Negro, Livio Nicola Carenza, Pasquale Digregorio +2
We investigate numerically, by a hybrid lattice Boltzmann method, the morphology and the dynamics of an emulsion made of a polar active gel, contractile or extensile, and an isotro…
