Transport of spherical microparticles in a three-dimensional vortex flow
This study explores the transport of microparticles in a three-dimensional stationary vortex generated in a microfluidic cross-slot geometry. Experiments and numerical simulations show that, when increasing particle diameter, particles are progressively excluded from the vortex core. Initially, small particles follow a Burgers vortex-like self-similar motion, but for larger particle diameters, deviations from this trend emerge due to fluid inertia and finite-size effects.
