dc.description.abstractThe turbulence modification of red blood cells is evaluated using a basic experimental approximation to blood, which specifically accounts for its particle-laden and dense concentration in vivo. The contribution of super absorbent polymer beads to a developing free shear layer is quantified using particle tracking velocimetry. Results showed that the presence of a particle-phase reduced mean velocities, kinetic energy, and the gradient of kinetic energy, implying that the free shear layer was diffused. Furthermore, similar fluid behaviour resulted between the suspension cases when Reynolds number was increased from 1,143 to 10,490. This suggests that red blood cells act to diffuse flow features that can subsequently lead to instabilities from which transitional and eventually turbulent behaviour can develop. These findings indicate that a two-phase model, specifically accounting for the dense particle-phase of blood, may be necessary for arterial blood flow where transition and turbulence can occur.en_US
