Aspiration patterns at Y = −0.02 m for (a) 6-μm particle (N = 54 at X = −0.75 m, Y = −0.02 m between Z = 0.00155 and −0.0255 m, ΔZ = 0.5 mm) and (b) 100-μm particle (N = 30 at X = −0.5 m, Y = −0.02 m between Z = 0.3365 and 0.3215 m, ΔZ = 0.5 mm). The top line indicates the trajectory for the particle released from the highest Z position and the bottom line indicates the trajectory for the particle released from the lowest Z position at the upstream (X,Y) coordinates.
