Embodiment Construction

[0017] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0018] combine Figure 1~6 , the experimental platform is mainly composed of water supply part I, driving part II, experimental part III and data measurement and acquisition part IV, in which experimental part III includes water distribution module (a) and test module (b). Before the experiment, the drum of the device was completely immersed in a pool filled with fluid to ensure the stability of the surrounding flow field during the high-speed rotation of the drum and to eliminate the influence of the external environment on the frictional resistance of the drum surface. During the experiment, the frequency modulation motor 18 fixed on the top of the device cavity 16 is used as the power source of the entire experimental platform, providing rotational power for the lower rotary drum to maintain high-speed and stable rotation. The rotary motion is transmitted to t...

Description

technical field [0001] The invention relates to an experiment platform, in particular to a drag reduction test experiment platform. Background technique [0002] With the increasingly serious energy consumption, it is imminent to save energy and reduce consumption. Its status in energy conservation and energy utilization improvement is self-evident. At present, relevant scholars at home and abroad have carried out extensive and in-depth theoretical research on the motion resistance between fluid and solid interfaces, and have successfully made significant progress in many aspects. However, the current research on drag reduction technology mainly includes three methods: theoretical analysis, numerical simulation, and model experiment. Theoretical analysis, data simulation and other methods ultimately need to be tested and verified by experiments. Through the experimental method to study the characteristics of fluid frictional resistance, many important turbulence phenomena ...
