Problems solved by technology

The spacing of the traditional narrow rectangular through narrow slits cannot be adjusted, and the bubble behavior in the channel can only be observed from the front viewing window, and important parameters such as bubble growth cannot be observed from the side
At the same time, in the traditional visualization experiment shooting method, the light source and the camera need to be arranged on the same side of the viewing window, and the light source illuminates the visualization glass from the front, forming a strong mirror reflection, which makes shooting difficult, affects the shooting effect, and brings great difficulties to the subsequent video processing.

Abstract

The invention discloses a narrow rectangular channel three-surface visualization device with adjustable spacing. The narrow rectangular channel three-surface visualization device comprises a camera (1), a two-dimensional guide rail (3), a light source (4), a light shield (5), a focusing lens (6) and a narrow rectangular channel, gaps of the narrow rectangular channel are adjustable, bubble growth can be observed from three sides, and a shooting scheme is provided in a targeted mode according to needs.

Description

technical field [0001] The invention relates to the field of flow channel observation, in particular to a three-side visualization device for a narrow rectangular channel with adjustable spacing. Background technique [0002] The narrow rectangular flow channel has the advantages of compact structure and large heat exchange area and is widely used. Narrow rectangular channels generally use a metal plate on one side as a heating plate, and quartz glass on the other side as a viewing window. The two sides are pressed to form a narrow rectangular channel. The distance between the traditional narrow rectangular through-narrow slits cannot be adjusted, and the bubble behavior in the channel can only be observed from the front viewing window, and important parameters such as bubble growth cannot be observed from the side. At the same time, in the traditional visualization experiment shooting method, the light source and the camera need to be arranged on the same side of the viewi...
