A study of the fluctuating velocity field in the developing region of a pulsating pipe flow is presented. Theoretically, three separate determinations of radial and axial perturbation velocity profiles were calculated involving varying degrees of analytical simplification. Experimentally, pulsating disturbances were created by a sinusoidal pressure wave exciter installed at the outlet of a 1.5 inch circular wind tunnel facility. Cross-wire anemometer measurements of the pulsating velocity components compared favorably with the parallel theoretical results. Likewise, experimental determinations of the phase angles between velocity and pressure signals compared favorably with analytical values. Author
