To investigate the driving force caused by motion of flagellum, the authors made the enlarged flagellum models which move in highly viscous liquid and measured the driving forces. The size and moving speed of the flagellum models were enlarged and determined according to scaling law. Reciprocal motion type and rotary motion type were prepared as test models, and the comparison was made in the same Reynolds number condition and in the same imposed power condition. As a result, rotary motion generated bigger force in the same Reynolds number condition, and reciprocal motion generated bigger force in the same power condition.
