Abstract

The invention discloses a wind tunnel-free Magnus effect demonstrating experiment device, which comprises a cylinder turntable, a turntable sliding rail, a turntable support directional moving wheel and a forced rotating shaft, and also comprises a water storage tank, a one-way water inlet tube, an air inlet control valve, a first level splitter plate, a second level splitter plate, a third level splitter plate and a back pressure energy dissipation plate. Compared with the prior art, the wind tunnel-free Magnus effect demonstrating experiment device has the advantages of obvious dynamic effect, high visualization degree, no sound pollution, stable flow state, low cost, small power consumption and small volume, and is suitable to be popularized in a hydraulic power and fluid laboratory of the university, a hydraulic power and fluid laboratory of the research institution and a science palace for popular science education.

Description

technical field [0001] The invention is a demonstration experiment device designed for the Magnus effect. Under the condition of no wind tunnel test bench, the demonstration experiment of the Magnus effect can be implemented by using the device of the invention. It belongs to the technical field of hydraulics and engineering fluid mechanics. Background technique [0002] The existing Magnus effect demonstration experiment is carried out on the wind tunnel test bench, relying on the wind tunnel to provide uniform and constant velocity flow. In the test, the motor provides the rotating power of the cylinder. , the Magnus effect occurs, and the cylinder moves on the track with the roller. The wind tunnel of the existing experimental device consumes a lot of power and has a lot of noise. The uniform constant-velocity wind provided by the wind tunnel can only be felt but not seen, and there are many auxiliary parts and occupy a lot of space. This kind of experimental device wit...
