Transparent channel with three optically independent axes for observation - Opt-3A-channel

在弗莱堡理工大学力学与流体动力学研究所，弯曲的、光学可及的流动几何将成为一个新的研究重点。市场上既没有用于调查此类流动的测试设备，也没有按照本文计划的程度对这些流动进行调查。由于大量的科学问题，一个可互换的测量部分是必要的。为了覆盖一个大的雷诺数范围，需要一个强大的泵，包括一个旁路，以及加热器来调整粘度。测试截面的折射率必须调整。时间分辨层摄影测量需要额外购买3D粒子跟踪测速系统，该系统由LED照明和摄像头组成，而IMFD目前还没有这些设备。国际货币基金组织已经提供了其他组件。

At the Institute of Mechanics and Fluid Dynamics of the TU Bergakademie Freiberg, flows in curved, optically accessible flow geometries shall be investigated as a new research focus. A test rig for investigating such flows is neither available on the market, nor have flows at all been investigated to the extent planned here. Due to the large number of scientific questions, an exchangeable measuring section is necessary. In order to cover a large Reynolds number range, a powerful pump including a bypass is required, as well as a heater to adjust the viscosity accordingly. The refractive index of the test section must be adjusted.Time-resolved, tomographic measurements require the additional purchase of a 3D particle tracking velocimetry system, consisting of LED lighting and cameras, which are not yet available at the IMFD. Additional components are already available on the IMFD.
