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.

在弗赖贝格工业大学力学和流体动力学研究所，弯曲的、光学可达的流动几何形状中的流动将作为一个新的研究重点进行研究。市场上既没有用于研究这种流动的试验装置，也没有对流动进行过本文所计划的研究。由于大量的科学问题，需要一个可更换的测量部分。为了覆盖大的雷诺数范围，需要包括旁路的大功率泵，以及相应地调节粘度的加热器。时间分辨的层析成像测量需要额外购买由LED照明和摄像机组成的3D粒子跟踪测速系统，IMFD目前还没有这种设备。IMFD上已经提供了其他组件。
