Concentration Matters: Enhancing Particle Settling in Narrow Tilted Channels
Dipankar Kundu, Florencio Balboa Usabiaga, Adolfo Vázquez-Quesada +1
Particles are known to sediment faster in containers with tilted walls than in vertical ones, a phenomenon known as the Boycott effect. In this work, we investigate how the tilt an…

Integral fractional viscoelastic models in SPH: LAOS simulations versus experimental data
Luca Santelli, Adolfo Vázquez-Quesada, Aizeti Burgoa +3
The rheological behaviour of a polymer was investigated by performing numerical simulations in complex flow and comparing them to experiments. For our simulations, we employed a Sm…

A semi-analytical solution for the lubrication force between two spheres approaching in viscoelastic fluids described by the Oldroyd-B model under small Deborah numbers
Alan Rosales-Romero, Adolfo Vázquez-Quesada, Marco Ellero +1
Viscoelastic fluids play a critical role in various engineering and biological applications, where their lubrication properties are strongly influenced by relaxation times ranging…
