FEM simulations of the flow conditions and RBC volume fraction (vol/vol) inside the PDMS-capillary device. (a) Simulated RBC concentration [see legend in (b)] in the central y–z-plane of the device. RBCs are injected into the central inlet while water is injected into the side inlets (white arrows). Here we replace the salt solution, as used in the experiment, by pure water. The fluids flow through a constriction and enter the quartz glass capillary at y = 0 µm. (b) Cross sections (x–z-plane) at different downstream positions along the main flow direction. The first cross section shows the red blood cell concentration in the constriction; the following three cross sections show the concentration in the capillary. (c) Simulated RBC concentration profiles and (d) velocity profiles along the z-axis at the downstream positions that are marked in (a) by the respective symbols.
