Abstract

The invention discloses a visual experiment device for fluid research. The device comprises a flow channel assembly which comprises a square frame, two opposite heat insulation plates disposed in thesquare frame, and electric heating plates. A flow channel is formed in a gap between the two heat insulation plates, and the electric heating plates are arranged on the plate faces, facing the flow channel, of the two heat insulation plates; observation windows are formed in the two opposite side walls of the square frame and are opposite to the gap between the two heat insulation plates. The structural design of the visual experiment device for fluid research can effectively simulate actual heating conditions and realize visual observation of bubble growth from the side surface.

Description

technical field [0001] The invention relates to the technical field of fluid visualization research, in particular to a visualization experimental device for fluid research. Background technique [0002] Plate-shaped fuel elements are used in the core design of small reactors because of the advantages of compact structure and large heat transfer area due to narrow rectangular coolant passages. In addition, due to the existence of latent heat of vaporization, the heat transfer coefficient of the two-phase boiling flow is greatly improved compared with that of the single-phase flow, and the boiling two-phase flow in the narrow rectangular flow channel is more complicated, and the flow patterns and flow patterns of the two-phase flow are various. In the flow process, there is also a violent phase change process, which can easily cause flow instability. Due to the narrow gap, the escape diameter of the boiling bubble becomes smaller and the frequency increases. Compared with the...
