Volumetric flow characterisation of a rectangular orifice impinging synthetic jet with single-camera light-field PIV

Abstract

The formation and evolution of volumetric flow structures from a rectangular orifice synthetic jet (퐴푅 = 10, 푅푒 = 550, 푆푟 = 0.0117, and 퐿표 = 0.0855푚) impinging on a flat plate is investigated using phase-locked single-camera light-field particle image velocimetry (LF-PIV). An impinging plate is located 24 orifice widths away from the rectangle orifice and this volumetric flow data is used to capture the mechanisms involved in the interaction. Flow statistics and structure information obtained by time-averaging and phase-averaging the volumetric data reveal the formation and evolution of three-dimensional vortical structures and sweeping vortex that characterise the flow-surface interaction.
