Embodiment Construction

[0059] In order to make the purpose, advantages and features of the present invention clearer, a low-pressure critical heat flux experimental system and experimental method proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific examples. The advantages and features of the present invention will become clearer from the following description. It should be noted that: the drawings are all in a very simplified form and use inaccurate proportions, which are only used to facilitate and clearly illustrate the purpose of the embodiments of the present invention; secondly, the structures shown in the drawings are often actual structures part; again, each drawing needs to display different emphasis points, and sometimes adopts different scales.

[0060] This embodiment provides a low-pressure critical heat flux experimental system. The experimental system parameters: pressure range 0.13-1MPa, temperature 10°...

Abstract

The invention relates to a low-pressure critical heat flux experimental system and an experimental method. The system includes a medium flow measurement pipe section, a preheating pipe section, an experimental heating pipe section, a medium ascending pipe section, a condenser, a medium descending pipe section, a first three-way valve, a connecting pipeline, a second three-way valve and a water supply unit; the first three-way The water outlet of the valve, the medium flow measurement pipe section, the preheating pipe section, the experimental heating pipe section, the medium ascending pipe section, the condenser, the medium descending pipe section, the second three-way valve, the connecting pipeline, and a water inlet of the first three-way valve along the The flow direction of the medium is communicated in sequence to form a circulation loop; the water supply unit communicates with the other water inlet of the first three-way valve for supplying circulation medium to the circulation loop. The proposal of the invention provides accurate and reliable data for the research on the heat transfer characteristics of the circulating flow and the critical heat flux density under the condition of the pulsed reactor.

Description

technical field [0001] The invention belongs to the research field of thermal hydraulic experiments of research reactors, and in particular relates to a low-pressure critical heat flux experimental system and an experimental method. Background technique [0002] Natural circulation is widely used in industry, and related technologies are disclosed in some published patents and non-patent literature. [0003] For example, Patent 1: Chinese Patent Publication No. CN102661845A discloses a visualized narrow rectangular natural circulation system, in which a narrow rectangular channel is used, and the flow phenomenon of the narrow rectangular channel is studied by a visualization method. Patent 2: Chinese Patent Publication No. CN106066235A discloses a supercritical water narrow channel natural circulation device and method, and its experimental device is used to study the heat transfer characteristics of a supercritical water reactor. [0004] The pulse reactor is a pool-type r...
