| Outline of Final Research Achievements |
We used incompressible Navier-Stokes and incompressible Euler equations to analyze local behavior of the particle trajectory on these flows. Also we implemented the numerical computation. More precisely, we focused on the hyperbolic flow configuration, swirl and no-slip boundary, and see how these behavior affect the flow behavior themselves. In particular, we studied time evolution of the maximum value and its position of the Navier-Stokes flow, separation phenomena of the Navier-Stokes flow with the no-slip boundary, and the ralation between boundary shape and the hyperbolic flow configuration of the Euler flow.
