| Outline of Final Research Achievements |
The deformation of objects in a flow and the motion of fine particles through interstitial fluid have been examined under the condition of the low Reynolds number. In the former subject, we experimentally investigated the deformation of the red blood cell caused by the fluid force in a flow and by the osmotic pressure difference. In the latter subject, the migration characteristics of fine particles suspension in a square channel with obstacles were evaluated by experiment and numerical simulation. In the experiment, the spatial distribution of the particle suspension, which flows in the quasi-two-dimensional square channel filled with glass particles, was closely observed. In the numerical simulation, the motion of granular assemblage though the particulate bed was calculated by the Stokesian dynamics approach and the relationship between the porosity of the bed and the behavior of the granular assemblage was quantitatively presented.
