Volumetric measurements of an adverse-pressure-gradient turbulent boundary layer using single-camera light-field PIV

  • 摘要: 作为一种新兴的体三维粒子图像测速技术,光场单相机三维粒子图像测速技术(Single-Camera Light-Field Particle Image Velocimetry,LF-PIV)能够仅用单个相机获得三维速度场,其结果已在许多复杂三维流动测量中得到验证。LF-PIV的优势主要在于其紧凑简便的硬件设备以及对光学窗口较宽松的要求。应用LF-PIV技术对一个自相似的逆压湍流边界层(Adverse Pressure Gradient Turbulent Boundary Layer,APG-TBL)进行测量,该实验在澳大利亚莫纳什大学(Monash University)航空航天与燃烧湍流研究实验室(Laboratory for Turbulence Research in Aerospace and Combustion,LTRAC)水洞中完成。实验对远、近壁面测量所得到的各600组瞬态三维流场数据进行分析验证,并与相同工况下的2D-PIV实验结果对比,证明基于DRT-MART重构技术的LF-PIV能够进行基本的湍流边界层测量。
