Embodiment Construction

[0017] The present invention will be described in more detail below in conjunction with the accompanying drawings:

[0018] combine Figures 1 to 6 , This experimental platform is mainly composed of water supply part I, driving part II, experimental part III and data measurement and acquisition part IV, wherein the experimental part III also includes water distribution module (a) and test module (b). Before the experiment, the device rotor 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 rotor, and to exclude the influence of the external environment on the frictional resistance of the rotor 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 whole experiment platform to provide rotational power for the lower rotor to maintain high-speed and stable rotation. Rotational motion is transmitted to ...

Abstract

The invention aims to provide an internal-rotation vertical type bionic drag-reducing testing experiment platform which comprises a pool, a torque signal coupler, a device base, a device frame, and a rotary drum, wherein a liquid is filled in the pool, the device frame is arranged in the pool and is of a non-closed structure, the device base is fixed on the device frame, a water distributing sealing cavity and a device cavity are fixed on the device frame, the water distributing sealing cavity is located in the device cavity, a frequency modulation motor is fixed on the device cavity, the torque signal coupler is installed on the inner wall of the device cavity through a signal coupler base, the frequency modulation motor is connected with the torque signal coupler through an elastic pin coupler, a water distributing hollow shaft is arranged in the water distributing sealing cavity, the upper end of the water distributing hollow shaft is connected with the torque signal coupler through a plum blossom coupler, the lower end of the water distributing hollow shaft is connected with the rotary cylinder, the rotary cylinder is arranged in the device frame, a water pump is communicated with the pool through a first water pipe, and the water pump is communicated with the water distributing sealing cavity through a second water pipe. The internal-rotation vertical type bionic drag-reducing testing experiment platform is small in volume, simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to an experimental platform, specifically a drag reduction test experimental platform. Background technique [0002] With the increasingly serious energy consumption, energy saving and consumption reduction are imminent, and its status in saving energy and improving energy utilization 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 the convection and the solid interface, 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. However, whether it is theoretical analysis or numerical simulation, the data obtained by model experiment has the highest accuracy and is closer to reality. Therefore, Theoretical analysis, data simulation and other methods ultimately ...
