Sub-Kolmogorov Intermittency and Multifractal Dissipation in Multiphase Turbulence
Marco Crialesi-Esposito, Alienor Riviere, Sergio Chibbaro
Multiphase turbulence displays stronger intermittency than its single-phase counterpart, yet the origin and geometrical organization of its most intense small-scale fluctuations re…
Spectrum correction in Ekman-Navier-Stokes turbulence
V. J. Valadão, G. Boffetta, F. De Lillo +2
The presence of a linear friction drag affects significantly the dynamics of turbulent flows in two-dimensions. At small scales, it induces a correction to the slope of the energy…
How small droplets form in turbulent multiphase flows
Marco Crialesi-Esposito, Guido Boffetta, Luca Brandt +2
The formation of small droplets and bubbles in turbulent flows is a crucial process in geophysics and engineering, whose underlying physical mechanism remains a puzzle. In this let…
Intermittency in turbulent emulsions
Marco Crialesi-Esposito, Guido Boffetta, Luca Brandt +2
We investigate the statistics of turbulence in emulsions of two-immiscible fluids of same density. We compute for the first time velocity increments between points conditioned to b…
The interaction of droplet dynamics and turbulence cascade
Marco Crialesi-Esposito, Sergio Chibbaro, Luca Brandt
The dynamics of droplet fragmentation in turbulence is described in the Kolmogorov-Hinze framework. Yet, a quantitative theory is lacking at higher concentrations when strong inter…
FluTAS: A GPU-accelerated finite difference code for multiphase flows
Marco Crialesi-Esposito, Nicolo Scapin, Andreas D. Demou +4
We present the Fluid Transport Accelerated Solver, FluTAS, a scalable GPU code for multiphase flows with thermal effects. The code solves the incompressible Navier-Stokes equation…
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…
