Description

technical field [0001] The invention relates to an experimental device, in particular to a flow field display experimental device for qualitative experimental research on flow field. Background technique [0002] Fluid flow is a very complex process, and many flow laws need to be studied. If only mathematical analysis is used, it is difficult to obtain correct results in most cases, but must rely on experiments to explore laws, verify theories, and solve practical problems in production. Flow field display and flow field simulation are two core tasks in the development of fluid mechanics. The flow field display technology is to better intuitively understand the distribution of the entire flow field, grasp the flow characteristics, and help establish theoretical analysis models. Obtain information from flow images, test theoretical analysis results, and discover new phenomena. There are many current flow field display technologies, which can be divided into the first genera...
