Abstract The formation and evolution of volumetric flow structures from a rectangular orifice synthetic jet ( AR = 10 , Re = 550 , Sr = 0.0117 , and L o = 0.0855 m ) 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.

具有单相机光场 PIV 的矩形孔口撞击合成射流的体积流量表征

摘要 利用锁相单相机光研究了矩形孔口合成射流( AR = 10 , Re = 550 , Sr = 0.0117 , L o = 0.0855 m )撞击平板的体积流结构的形成和演化。场粒子图像测速 (LF-PIV)。撞击板位于距矩形孔口 24 个孔口宽度处，该体积流量数据用于捕获相互作用中涉及的机制。通过对体积数据进行时间平均和相位平均获得的流动统计和结构信息揭示了表征流-面相互作用的三维涡结构和扫掠涡的形成和演化。
