Sequential snapshots of RBCs (red) and platelets (white) traveling in the four MA microchannels with BNR = (A) 8, (B) 5.4, (C) 3, (D) 2.2, during the simulation time of 1.3 seconds.

The hematocrit level is 10% in the microchannel. The timestamp increases sequentially from snapshot (I) to (III). RBCs are initially placed in the parent vessels. Solvent particles are omitted for clarity. The corresponding trajectories of RBCs (red curves) and platelets (white curves) are plotted in (IV). The inlet (right end of the microchannel) blood flow velocity is 1.5 mm/s for all the four MAs.
