Dean flow-coupled inertial focusing in curved channels.
Passive particle focusing based on inertial microfluidics was recently introduced as a high-throughput alternative to active focusing methods that require an external force field to manipulate particles. In inertial microfluidics, dominant inertial forces cause particles to move across streamlines and occupy equilibrium positions along the faces of walls in flows through straight micro channels...

متن کاملDean Flow-coupled Inertial Focusing for Ultra-high-throughput Particle Filtration
Particle manipulation represents an important and fundamental step prior to counting, sorting and detecting bioparticles. In this study, we report dean-coupled inertial focusing of particles in flows through a single curve microchannel at extremely high channel Reynold numbers (~325). We found the lateral particle focusing position, xf to be fixed and largely independent of radius of curvature ...
متن کاملFundamentals of elasto-inertial particle focusing in curved microfluidic channels.
Elasto-inertial focusing in viscoelastic fluids has attracted increasing interest in recent years due to its potential applications in particle counting and sorting. However, current investigations of the elasto-inertial focusing mechanisms have mainly been focused on simple straight channels with little attention being paid to curved channels. Herein, we experimentally explore the elasto-inert...
متن کاملDean instability in double-curved channels.
We study the Dean instability in curved channels using the lattice Boltzmann model for generalized metrics. For this purpose, we first improve and validate the method by measuring the critical Dean number at the transition from laminar to vortex flow for a streamwise curved rectangular channel, obtaining very good agreement with the literature values. Taking advantage of the easy implementation...
