Abstract
Methods used in estimating tail pipe radiation characteristics are reviewed. The pressure reflection coefficient and the radiation impedance of a tail pipe with a moving medium are evaluated form standing wave measurements at discrete positions. Empirical relations of the pressure reflection coefficient (modulus and phase angle) and the radiation resistance and reactance in the presence of mean flow, are derived from experiments observations in circular pipes of different diameters.
