Motion studies with fluorescent beads, RBC, and WBC in dilute and concentrated suspension flows indicate that the erratic transport has a common mathematical basis

Translational invariance was the keystone in a method that demonstrated the nature of tracer motions in suspension flows in 50 and 100 μm channels. The experimental protocol collected related ensembles of time increments that shared a well-defined initial condition. The existence of common functional shapes suggests that the mathematics describing the erratic elements in all suspension flow is more identical than is reflected in the literature, which distinguishes among diffusion, dispersion, and anomalous diffusion.
