J0202-2-2 Numerical and experimental study on spira1 motion of microbe's flagellum

Abstract

Micobe can move smoothly in water environment with high efficiency, which could offer new ideas for future micro machines. In this study, we investigated the spiral moving behavior of flagellum by using numerical and experimental models. We simulated euglena's fluid environment of Re number of 10^<-4>. The optimal roll number of the spiral shapes in terms of flow velocity and driven force was studied and the existence of most efficient roll number was suggested.
