Visual test system

The invention relates to a visual test system. The system comprises a fuel assembly; a pipeline system which is used for enabling a flowing working medium to flow in the fuel assembly; and a measurement control device which is used for collecting the measurement parameters and controlling all devices of the pipeline system to work according to the collected measurement parameters so as to obtain the speed distribution and the pressure drop distribution in the fuel assembly. According to the system, the pressure drop distribution and the speed distribution in the fuel assembly can be measured,by reasonably designing the fuel assembly and selecting the flowing working medium, the data of a model test can be applied to a prototype test, the test frequency is reduced, the test difficulty is reduced, and the test cost is saved. 本发明涉及一种可视化试验系统，该系统包括：燃料组件；管路系统，用于使得流动工质能够在燃料组件内部流动；测量控制装置，用于采集测量参数，并根据采集的测量参数控制所述管路系统各器件工作，获得燃料组件内部的速度分布和压降分布。本发明可以测量燃料组件内部的压降分布和速度分布，通过合理的设计燃料组件和选择流动工质，可以将模型试验的数据应用到原型试验中，减小试验次数，降低试验难度和节约实
