Abstract

The invention discloses a curved neck type model support device for soap film water tunnel experiments, relates to the field of fluid mechanics, and comprises a curved neck with a height difference at both ends and a beam with closed loops at both ends; the curved neck consists of A thin wire is bent, and there is a height difference between the front and rear ends of the curved neck, the rear end of the curved neck is higher than the front end of the curved neck, and the front end of the curved neck is inclined downward; The curved neck can conveniently adjust the position of the six degrees of freedom of the model; the filaments are fixed by the closed loops at both ends of the beam. The invention can conveniently replace the experimental model in the soap film water hole experiment, prevent the backflow of the soap liquid, and can adjust the six degrees of freedom. The material used is thin steel wire, which is easy to obtain and low in cost. The thin steel wire is easy to bend, But the rigidity is strong, which is convenient for the manufacture and use of the device.

Description

technical field [0001] The invention belongs to the field of fluid mechanics, and relates to a soap mold water hole experiment device, in particular to a model support device for a soap film water hole experiment. Background technique [0002] The soap film water tunnel device is an experimental device for studying two-dimensional flow fields. Relatively mature now are the vertical soap film water hole device with higher speed and the lower horizontal or inclined soap film water hole device with speed. [0003] The invention proposes an experimental model supporting device suitable for a vertical soap film water hole device. Such as figure 1 As shown, the vertical soap film water hole device is mainly composed of an upper water storage device, a soap film support frame, and a recovery tank from top to bottom. The upper water storage device is used to hold the soap liquid, which is composed of an inner cup and an outer cup. At the beginning, keep the soap liquid in the inn...
