| Research Abstract |
Synchronization of spring-loaded cylinders in uniform flow was analyzed numerically. In the regime of Reynolds number where vortex separation is observed, synchronization of two cylinders with different natural frequencies was observed. The coupling function of phase model of this system was obtained by the data of the motions of the center of mass. Peristaltic pumping of true slime mold was also analyzed. Model consisting of chemical transport and boundary motion and model consisting of simple phase equation with Neumann boundary condition with non-zero gradient were analyzed. Characteristic spatio-temporal pumping pattern was reproduced.
