Fluid-inertia torques from particle-shape symmetry
L. Sundberg, F. Candelier, N. Fintzi +4
Numerical simulation of particle motion in fluids at low particle Reynolds numbers is often based on empirical force and torque models obtained by fitting force and torque from ab-…
Inertial effects on the interphase drag force and rheology of dilute suspensions of buoyant droplets at low Reynolds number
Nicolas Fintzi, Jean-Lou Pierson
In this work, we compute the hydrodynamic force and the first and second moments of force acting on a translating spherical droplet immersed in a uniform flow using the reciprocal…
Averaged equations for disperse two-phase flow with interfacial properties and their closures for dilute suspension of droplets
Nicolas Fintzi, Jean-Lou Pierson
This article provides a derivation of the averaged equations governing the motion of dispersed two-phase flows with interfacial transport. We begin by revisiting the two-fluid form…
Buoyancy driven motion of non-coalescing inertial drops: microstructure modeling with nearest particle statistics
Nicolas Fintzi, Jean-Lou Pierson, Stéphane Popinet
In this study, we analyze the various arrangements that droplets can form within dispersed buoyant emulsions, which we refer to as the study of microstructure. To this end, we have…
