Outline of Final Research Achievements

The dynamics of the particles with hydrodynamic interaction was simulated. We examined the interaction of the particles with chirality in two dimensional channel flow.
We also examined the sedimentation of spherical particles in cylindrical tube. A speed up of the sedimentation, which is called Boycott effect, could be confirmed when the tube was tilted.
In the dynamics of arbitrary shaped particle, the analytical calculation is important although the simulation is important. We discussed the dynamics of the propeller-like particles in rotating electric field using Fokker Planck equation. The results showed the direction of the migration of the particle depends on the chirality. The separation method was discussed due to the chirality.
