 note = {In order to clarify the characteristics of pulsating flow in a flexible tube and a rigid tube, the fluctuating pressures were measured on the surface of the test tube. The influences of rotation frequency and stroke length as the parameter of the pulsating flow on drag reduction were examined. The coefficient of friction in the case of a pulsating flow does not change compared with that of a steady flow. Namely, it is clear that the coefficient of friction in a flexible tube is smaller than that in a rigid tube, in the case of the pulsating flow. This result is related to the turbulence of the fluctuating pressure.},
