Complex Spatio-Temporal Patterns in Red Blood Cells Flows

Inhalt:
A low concentration red blood cells (RBCs) flow in unsteady conditions was investigated in a micro-channel. A pressure strength of different intensity was imposed at the microchannel inlet and the flow was monitored optically. The movies acquired were analysed by the Particle Image Velocimetry to extract the spatio-temporal flow maps related to the RBCs velocity on the horizontal and vertical direction, and to the velocity gradients. The results obtained has enriched the characterization of the three RBCs behavioral flow patterns {Weak Activity, Vorticity, Alignment} established in a previous work leading to a deeper understanding of the conditions for the particle displacements in the micro-channel.
