Effect of post shape on cell trajectory at moderate to high Re regime. In order to keep the critical size same for different post shapes, the gap between two adjacent posts is calculated based on Ref. 66, which results in gR > gT > gC. The injected cells in all three designs are of the same size. Note that for the circular and triangular posts, the cell follows the bumped mode, while in the device with square posts, it follows the zigzag mode.
