An axial velocity of a laminar, fully-developed oscillatory flow in a curved pipe was investigated experimentally and numerically. A laser doppler velocimeter was used to measure the axial velocity. The measured result was in good agreement with the numerical analysis, and the effect of oscillatory Dean number D and Womersley number α on velocity near the inside wall became larger than that near the outside wall under the condition of comparatively large Dean number and moderate Womersley number.
