Non-reciprocal coalescence-breakup dynamics in flowing concentrated emulsions

Ivan Girotto, Andrea Scagliarini, Lei Yi, Roberto Benzi et autres

Abstract Dense stabilized emulsions are mixtures of immiscible fluids where the high-volume fraction droplet dispersed phase is stabilized against coalescence by steric interactions. The production of emulsions-a key process in food, cosmetics and chemical industries-involves high-shear flows, elastic and steric interactions, and …

An FFT-oriented performance analysis and optimization of Quantum ESPRESSO on top-tier EuroHPC systems

Fabrizio Ferrari Ruffino, Francesco Andreucci, Pietro Delugas, Angela Acocella et autres

Density functional theory (DFT), combined with the plane-waves (PW) representation, forms the basis of a large class of first-principles materials simulation codes. In these applications, Fast Fourier Transforms (FFTs) constitute the core computational kernel that strongly impacts overall performance. In the Quantum …

Non-reciprocal coalescence-breakup dynamics in concentrated emulsions

Ivan Girotto, Andrea Scagliarini, Lei Yi, Roberto Benzi et autres

Dense stabilized emulsions are mixtures of immiscible fluids where the high-volume fraction droplet dispersed phase is stabilized against coalescence by steric interactions. The production of emulsions involves high-shear flows and it is well known that at a critical volume fraction the emulsion …

Divergence of Critical Fluctuations on Approaching Catastrophic Phase Inversion in Turbulent Emulsions

Lei Yi, Ivan Girotto, Federico Toschi, Chao Sun

Catastrophic phase inversion, the breakdown of a concentrated emulsion characterized by the most puzzling sudden feature, is crucial in numerous industrial applications. Here we combine well-controlled experiments and fully resolved numerical simulations to study the critical dynamics of catastrophic phase inversion in …

Lagrangian statistics of concentrated emulsions

Ivan Girotto, Andrea Scagliarini, Roberto Benzi, Federico Toschi

The dynamics of stabilised concentrated emulsions presents a rich phenomenology including chaotic emulsification, non-Newtonian rheology and ageing dynamics at rest. Macroscopic rheology results from the complex droplet microdynamics and, in turn, droplet dynamics is influenced by macroscopic flows via the competing action …
