(a) Sketch of the selected observation positions at 30%, 50% and 70% relative width of the channel in straight and curved channels, respectively. (b) Correlation images of normalized g2 (τ = 20 ms) at positions I–III in a straight channel and position IV–VI in a curved channel with radius R = 500 µm. The average flow velocity was 10 µm s−1. The red lines in frames IV–VI are oriented parallel to the flow direction. |
