Abstract
This work describes an experimental study of the flow field and wall pressure fluctuations induced by a subsonic jet tangentially overflowing a rigid flat plate. Measurements are carried out at a fixed Mach number varying the radial distance of the flat plate in three positions. The free jet case is tested as well, to better evidence the different phenomenology. Pressure fluctuations are measured with flush mounted transducer pairs translated in the streamwise direction, whereas the mean and fluctuating velocity fields are measured through a static Pitot-tube and a Hot Wire anemometer respectively. The overall flow physics is studied in terms of averaged velocity fields and high-order statistical moments of the velocity fluctuations. The wall pressure statistics are analyzed in terms of several indicators, including the time averaged, the root mean squares and the overall sound pressure level of the pressure fluctuations.
