Bubbles enable volumetric negative compressibility in metastable elastocapillary systems
Davide Caprini, Francesco Battista, Pawel Zajdel +11
Although coveted in applications, few materials expand when subject to compression or contract under decompression, i.e., exhibit the negative compressibility phenomenon. A key ste…
The aerodynamic response of a pre-stressed elastically nonlinear aileron
Giovanni Corsi, Francesco Battista, Paolo Gualtieri +1
We study the aerodynamic response of a pre-stressed curved aileron. Whilst the fluid flow is standard (high Reynolds air flow undisturbed at infinity), the structure is designed to…
Superhydrophobic surfaces to reduce form drag in turbulent separated flows
J. -P. Mollicone, F. Battista, P. Gualtieri +1
The drag force acting on a body moving in a fluid has two components, friction drag due to fluid viscosity and form drag due to flow separation behind the body. When present, form…
Particles in turbulent separated flow over a bump: effect of the Stokes number and lift force
Jean-Paul Mollicone, Mahshid Sharifi, Francesco Battista +2
Particle-laden turbulent flow that separates due to a bump inside a channel is simulated to analyse the effects of the Stokes number and the lift force on the particle spatial dist…
Drag reduction induced by superhydrophobic surfaces in turbulent pipe flow
Roberta Costantini, Jean-Paul Mollicone, Francesco Battista
The drag reduction induced by superhydrophobic surfaces is investigated in turbulent pipe flow. Wetted superhydrophobic surfaces are shown to trap gas bubbles in their asperities.…
Curvature effects in turbulent premixed flames of H/Air: a DNS study with reduced chemistry
Gabriele Rocco, Francesco Battista, Francesco Picano +2
Data from a three-dimensional Direct Numerical Simulation of a turbulent premixed Bunsen flame at a low global Lewis number are analyzed to address the effects of the curvature on…
Fractal scaling of turbulent premixed flame fronts: application to LES
Francesco Battista, Guido Troiani, Francesco Picano
The fractal scaling properties of turbulent premixed flame fronts have been investigated and considered for modelling sub-grid scales in the Large-Eddy-Simulation framework. Since…
Turbulence modulation in heavy-loaded suspensions of tiny particles
P. Gualtieri, F. Battista, C. M. Casciola
The features of turbulence modulation produced by a heavy loaded suspension of small solid particles or liquid droplets are discussed by using a physically-based regularisation of…
Effect of geometry and Reynolds number on the turbulent separated flow behind a bulge in a channel
Jean-Paul Mollicone, Francesco Battista, Paolo Gualtieri +1
Turbulent flow separation induced by a protuberance on one of the walls of an otherwise planar channel is investigated using Direct Numerical Simulations. Different bulge geometrie…
Turbulent mixing of a slightly supercritical Van der Waals fluid at Low-Mach number
Francesco Battista, Francesco Picano, Carlo Massimo Casciola
Supercritical fluids near the critical point are characterized by liquid-like densities and gas-like transport properties. These features are purposely exploited in different conte…
