Numerical investigation of the dynamics of a rigid spherical particle in a vortical cross-slot flow at moderate inertia

Abstract: The study of flow and particle dynamics in microfluidic cross-slot channels is of high relevance for lab-on-a-chip applications. In this work we investigate the dynamics of a rigid spherical particle in a cross-slot junction for a channel height-to-width ratio of 0.6 and at a Reynolds number of 120 for which a steady vortex exists in the junction area. Using an in-house immersed-boundary-lattice-Boltzmann code, we analyse the effect of the entry position of the particle in the junction and the particle size on… Show more

“…Among these, the Lattice Boltzmann Method (LBM) [15], Fluid-Structure Interaction (FSI) [16], and Particle Tracing (PT) [17] are notable. Kechagidis et al [18] used the LBM method for particle migration analysis in microfluidic cross-slot channels. Ying and Lin [19] used the PT method to predict the migration path of particles in serpentine channels.…”
