Abstract

The invention belongs to a simulation device for research of a single-phase and two-phase bubble behavior and a flow pattern, which comprises a thermal conduction copper plate, a visual window, an electric heating component, a bottom pressure-bearing body, a pressure measuring component and other components. The thermal conduction copper plate and a concave flow channel of a rectangular narrow seam of the visual window for a closed channel of the rectangular narrow seam, and thus an experimental device of the rectangular narrow seam for research on single-phase and two-phase three-dimensional visualization is formed. The single-phase flow state, the three-dimensional bubble state, the flow pattern conversion and other evolution laws in the rectangular narrow seam channel can be observed based on wide-surface and narrow-surface three-dimensional visualization, and conditions can be provided for in-depth revealing of flow and heat transfer mechanism in the narrow channel.

Description

technical field [0001] The invention belongs to a simulation device for single-phase and two-phase bubble behavior and flow pattern research, in particular to a rectangular narrow slit experimental device for single-phase and two-phase stereoscopic visualization research. The device can meet the three-dimensional visualization research of single-phase flow state, two-phase bubble behavior and flow pattern in the rectangular narrow slit channel. Background technique [0002] Rectangular slot structures are widely used in cooling systems in nuclear reactors, aerospace and electronics industries. In nuclear reactors, the core coolant channel of the plate-type fuel element is a narrow-slit rectangular channel. The plate-type fuel element is used by some propulsion power reactors, research reactors, etc. because of its high fuel consumption and high specific power. The stack type of output power density is adopted, and its coolant channel is a typical flat rectangular narrow sli...
