Progress on Swimming Mechanism of Flagellar Bacteria

Abstract:

Some types of bacteria swim through rotating their flagella. The swimming mechanism of bacteria during flagella bundling and tumble process is analyzed. The effects of body rotation and flagellum′s polymorphic transitions on bundling processes and the wall effect phenomenon are also discussed. Finally, based on dynamics similarity, a new microrobot module is put forward to further studying the flagella swimming phenomena. The research would be very helpful for constructing the bionic swimming robots under the low Reynolds number.
