Numerical simulations of the pressure-driven flow of pairs of rigid spheres in elastoviscoplastic fluids
Giancarlo Esposito, John Tsamopoulos, Massimiliano Maria Villone +1
We investigate through numerical simulations the hydrodynamic interactions between two rigid spherical particles suspended on the axis of a cylindrical tube filled with an elastovi…
Elasto-visco-plastic flows in benchmark geometries: II. Flow around a Confined Cylinder
Milad Mousavi, Yannis Dimakopoulos, John Tsamopoulos
We examine computationally the two-dimensional flow of elastoviscoplastic (EVP) fluids around a cylinder symmetrically placed between two plates parallel to its axis. The Saramito-…
Hydrodynamic interaction between coaxially rising bubbles in elasto-visco-plastic materials: Bubbles with a wide range of relative sizes
Athanasios Kordalis, Yannis Dimakopoulos, John Tsamopoulos
We consider the buoyancy-driven rise and interaction between two gravity-aligned bubbles of wide radii ratio and constant volume in an elasto-visco-plastic (EVP) material, extendin…
Buoyancy induced motion of a Newtonian drop in elastoviscoplastic materials
Giancarlo Esposito, Yannis Dimakopoulos, John Tsamopoulos
We investigate theoretically the buoyancy-driven motion of a viscous drop in a yield-stress material, incorporating elastic effects represented by the Saramito-Herschel-Bulkley con…
