流体力学领域国际合作研究大尺度折射率匹配流动系统

In recent international collaboration, Idaho National Laboratory (INL) and Universität Erlangen (UE)
have developed large MIR flow systems which are ideal for joint graduate student education and research. The benefit
of the MIR technique is that it permits optical measurements to determine flow characteristics in complex passages and
around objects to be obtained without locating a disturbing transducer in the flow field and without distortion of the
optical paths. The MIR technique is not new itself; others employed it earlier. The innovation of these MIR systems is
their large size relative to previous experiments, yielding improved spatial and temporal resolution. This report will
discuss the benefits of the technique, characteristics of the systems and some examples of their applications to complex
situations. Typically their experiments have provided new fundamental understanding plus benchmark data for
assessment and possible validation of computational thermal fluid dynamic codes. 德国LaVision PIV/PLIF粒子成像测速场仪 Imager SX PIV相机 用于粒子成像测速(PIV)的荧光示踪粒子
