EXPLORING THE INTERACTION OF RED BLOOD CELL ANALOGS WITH TURBULENCE USING PARTICLE TRACKING VELOCIMETRY
Краткое описание
Particle Tracking Velocimetry (PTV) is performed in order to study the interaction of red blood cell analogs with turbulence. Super water absorbent deformable hydrogel beads are used to represent red blood cells (RBC) in different suspending fluids. Excellent optical matching is observed between the hydrogel beads and the suspending fluids. The results of PTV measurements show significant differences between the velocity patterns in the presence and absence of the hydrogel beads. However, the velocity patterns appear comparable between the different solutions. In order to analyze the detailed interaction of red blood cell analogs with turbulence, a new experiment has also been designed. An approximately homogeneous turbulent shear flow is generated in a large-scale tank by towing a shear generator consisting of a plane parallel-rod grid. In this large-scale experiment, large- and small-scale coherent structures will be investigated with and without RBC analogs in the absence of the complex wall effects.
