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 density experiment system and an experiment method. The system comprises a medium flow measuring pipe section, a preheating pipe section, anexperiment 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, a water outlet of the first three-way valve, the medium flow measuring pipe section, the preheating pipe section, the experiment heating pipe section, the medium ascending pipe section, thecondenser, the medium descending pipe section, the second three-way valve, the connecting pipeline and one water inlet of the first three-way valve are sequentially communicated in the flowing direction of a medium, and therefore a circulation loop is formed. The water supply unit is communicated with the other water inlet of the first three-way valve and is used for supplying a circulating medium to the circulating loop. Accurate and reliable data are provided for research on the circulating flow heat exchange characteristic and the critical heat flux density under the working condition of the pulse 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...
