Caption : comparison of dld unit cells with the same flow rate and critical diameter. the upper version has a round obstacle and a gap of 16.5 µm, the lower has a pointed vertex and a gap of 22 µm. the left panel shows the velocity field, the right panel shows the shear rate. the scale is the same for each. a line is drawn vertically, 1 µm away from the gap edge, and we compute the average shear rate along this line (dashed arrow). the spatially averaged shear rate is 36% lower when using obstacles with sharp vertices.

Caption : performance of the curate system and dld separation under different modes of operation. no difference in performance is observed between the 3 modes of operation.
