Abstract: Pressure and velocity measurements were performed at the orifice plate and along the pipe, resulting in the time-mean and oscillating velocity radial profiles as well as pressure and velocity amplitudes axial distributions. The data acquired indicate that velocity oscillation is primarily manifested in the central core of the flow and that the jet boundary oscillates in an axisymmetric mode. Effective discharge coefficient was evaluated from a reference flow rate measured by a supersonic, calibrated nozzle. Velocity and pressure oscillation effects on the coefficient are presented. Theoretical considerations and utilizing of the experimental data enabled estimation of the discharge coefficient dependence on the jet cross-sectional area oscillation. This oscillation can decrease or increase significantly a value of the discharge coefficient resulting from the square root correction only.
