In case of rectangular cross section microfluidic channel and particle size comparable to the channel size, consequences of the combination of confining geometries, inertia, and particle concentration have not been characterized. In this paper, the authors study the effects of particle concentration and channel geometry on inertial focusing. The authors find that the location and number of focusing positions depend on the linear number density of particles along the channel. The linear number density is a function of channel cross section and number of particles.
