The fragmentation-induced fluidisation of pyroclastic density currents [PDF]

open access: yesNature Communications, 2023
Pyroclastic density currents (PDCs) are the most lethal volcanic process on Earth. Forecasting their inundation area is essential to mitigate their risk, but existing models are limited by our poor understanding of their dynamics.

Microrollers flow uphill as granular media [PDF]

open access: yesNature Communications, 2023
Pour sand into a container and only the grains near the top surface move. The collective motion associated with the translational and rotational energy of the grains in a thin flowing layer is quickly dissipated as friction through multibody interactions.

Methodology for hydraulic characterisation of the sand filter backwashing processes used in micro irrigation [PDF]

open access: yesMethodsX, 2020
The correct operation of the backwashing process in sand filters used in micro irrigation determines directly the effectiveness of the subsequent filtration processes, and consequently the micro irrigation systems maintenance. As backwashing involves the

Glassy dynamics in active epithelia emerge from an interplay of mechanochemical feedback and crowding [PDF]

open access: yesNature Communications
Glassy dynamics in epithelial tissues remain a subject of debate, as theory predicts its emergence only at unrealistically low cellular activity, yet experimental studies have shown glassy dynamics at physiologically active conditions.

Fluidisation of spherocylindrical particles: computational fluid dynamics–Discrete element method simulation and experimental investigation

open access: yesEngineering Applications of Computational Fluid Mechanics
The fluidisation of spherocylindrical particles is often involved in the fields of biomass combustion, drug delivery and food drying. By spherocylindrical particles, we mean elongated spherical particles like non-spherical capsule pills and pulverised ...

Fluidisation of iron-based oxygen carrier for chemical looping combustion [PDF]

open access: yesE3S Web of Conferences, 2019
The study focuses on the fluidisation of an iron-based material for chemical looping combustion. The Fe/FexOy system can act as an oxygen carrier. This material can be used to transfer the oxygen in the chemical looping combustion ensuring easy CO2 ...

Evaluation of CO2 Adsorption Parameters in Fluidised Zeolite 13X Beds Using Non-Linear Multivariate Optimisation

open access: yesSeparations, 2023
This work is part of a research project aimed at studying potential sorbents for CO2 capture. The main parameters characterising the adsorption process of zeolite 13X were derived with the aim of overcoming the limits of experimental analysis and thus ...
