Description
technical field [0001] The invention relates to a rotating non-smooth surface drag reduction measurement experimental device. Background technique [0002] The bionic non-smooth surface drag reduction technology has always been one of the hot research issues at home and abroad. Its drag reduction effect is obvious, and it will not bring extra energy consumption to the equipment, nor will it take up space, and it is green and environmentally friendly. Therefore, it is more important to conduct quantitative research on bionic non-smooth surface technology by using experimental methods. [0003] In the traditional research of fluid mechanics, most of the experimental equipment such as water tunnels, wind tunnels, and pools are used. The above-mentioned experimental techniques not only occupy a large area and are bulky, but also require a lot of expenses, so that they will be used in many aspects. Subject to certain limitations and restrictions. If the experiment is carried o...
