Great to host Profs Gerry Fuller, Jeff Giacomin and Marco Ellero as part of the 1st Swansea Complex Fluids Day 2024 yesterday! Lots of discussion: biorheology, chirps, shear thickening, modelling, microfluidics and lots of coffee extraction! @SwanseaUni @SUSciEng @BritSocRheology

Matthew Bedding-Tyrrell proposed an easy&efficient way to calculate permeability and wall shear stress within tissue engineering scaffold using data-driven approach. Thanks for the collaboration / contribution from @pEganPhD @nithiarasu @Complexflowlab

It is commonly known that mechanical stimulation, for example, wall shear stress (WSS), can affect cellular behaviours. In vitro experiments have been performed by applying fluid-induced WSS to inv...

SPH simulations of DST in Peter Angerman et al's new paper: Microstructural smoothed particle hydrodynamics model and simulations of discontinuous shear-thickening fluids
pubs.aip.org
Despite the recent interest in the discontinuous shear-thickening (DST) behavior, few computational works tackle the rich hydrodynamics of these fluids. In this

Phys. Rev. Fluids 8, 114302 (2023) - Shape of a frictional fluid finger
journals.aps.org
Compared with Saffman-Taylor fingers, which result from long-range viscous forces, `frictional fingers' are a distinct hydrodynamic phenomenon that is entirely governed by short range forces. Here we...
