The axial velocity of a laminar, fully-developed pulsating flow in curved circular pipes has been measured by means of a laser doppler velocimeter in a wide range of various parameters, i. e. radius ratio of pipes R/a, mean Dean number D^-, Womersley number α and flow rate ratio η. The experimental results agree well with the solutions of the numerical analysis. The instantaneous velocity measured is classified into a time-mean component and varying ones and the effects of parameters on them are discussed. Explanations are given for the complicated behavior of the curved pipe pulsating flows.
