Location of particle streak as a function of Reynolds number. The full symbols (full circles) represent the lift force-dominated regime, and the open symbols (open circles) represent the Dean drag force-dominated regime. (a) and (b) are the case of small particles (2.45–4.16–5.9 µm) in the square and modified square wave microchannels, respectively, and (c) and (d) are the case of large particles (8.0–10.0–12.0 µm) in the square wave and modified square wave microchannels, respectively. The standard deviation around the mean value of the particle location is also represented for each point.
