Viscoelastic coarsening of quasi-2D foam
Chiara Guidolin, Jonathan Mac Intyre, Emmanuelle Rio +2
Foams are unstable jammed materials. They evolve over timescales comparable to their "time of use", which makes the study of their destabilisation mechanisms crucial for applicatio…
Machine learning and predicting the time dependent dynamics of local yielding in dry foams
Leevi Viitanen, Jonatan R. Mac Intyre, Juha Koivisto +2
The yielding of dry foams is enabled by small elementary yield events on the bubble scale, "T1"s. We study the large scale detection of these in an expanding 2D flow geometry using…
The effect of pressure pulsing on the mechanical dewatering of nanofiber suspensions
Marko Korhonen, Antti Puisto, Mikko Alava +1
Dewatering processes are invariably encountered in the chemical manufacturing and processing of various bioproducts. In this study, Computational Fluid Mechanics (CFD) simulations…
Coarsening and mechanics in the bubble model for wet foams
Kseniia Khakalo, Karsten Baumgarten, Brian P. Tighe +1
Aqueous foams are an important model system that displays coarsening dynamics. Coarsening in dispersions and foams is well understood in the dilute and dry limits, where the gas fr…
Friction controls submerged granular flows
Juha Koivisto, Marko Korhonen, Mikko J. Alava +3
We investigate the coupling between interstitial medium and granular particles by studying the hopper flow of dry and submerged system experimentally and numerically. In accordance…
Start-up inertia as an origin for heterogeneous flow
Marko Korhonen, Mikael Mohtaschemi, Antti Puisto +2
For quite some time non-monotonic flow curve was thought to be a requirement for shear banded flows in complex fluids. Thus, in simple yield stress fluids shear banding was conside…
