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…
Elasto-visco-plastic flows in benchmark geometries: I. 4 to 1 Planar Contraction
Milad Mousavi, Yannis Dimakopoulos, John Tsamopoulos
We present predictions for the flow of elastoviscoplastic (EVP) fluids in the 4 to 1 planar contraction geometry. The Saramito-Herschel-Bulkley fluid model is solved via the finite…
