Abstract
In this article, surface tension driven blood flow in a microchannel with red blood cells (RBCs) aggregation resulting in the different viscosity by handling sloping condition has been studied. According to the non-homogeneous and non-Newtonian characteristics, the heavier RBCs are driven by surrounding lighter plasma with the effect of blood aggregation which is influenced by the ratio of gravity, viscosity and capillary force in a surface tension driven blood flow system. However, the capillary force and viscosity have been decided in fabrication process. By changing the slope, we found the gravity made a great impact on hematocrit ( volume percentage of cells), thus, the viscosity was changed.
