The invention relates to the technical field of supercritical carbon dioxide solar cavity type heat absorbers, in particular to a device and method for measuring heat transfer fluidity of fluid in anelectrical energy system heat absorber. The experimental device comprises a closed circulation loop which comprises a gas supply and storage device, a pressurization and temperature rise device, a solar cavity type heat absorber and a pressure reduction and temperature reduction device which are arranged in sequence; the experimental device also comprises a solar heat collector which is used for heating the supercritical carbon dioxide in the solar cavity type heat absorber; and a temperature and pressure quality detection device which is used for detecting the mass flow rate flowing through the solar cavity type heat absorber and the temperature and pressure of the supercritical carbon dioxide before and after the solar cavity type heat absorber so as to calculate the heat transfer flow characteristic of the supercritical carbon dioxide in the solar cavity type heat absorber. The problems that in the prior art, flow and heat transfer characteristics of supercritical carbon dioxide inthe solar cavity type heat absorber only exist in the numerical simulation stage, and accurate parameters cannot be obtained can be solved.
Description
Technical field [0001] The present invention relates to the field of supercritical carbon dioxide solar cavity heat absorbers, and more particularly to apparatus and methods for measuring fluid heat transfer fluidity in electrical energy systems. Background technique [0002] With the development and utilization of climate warming and the energy crisis, the development and utilization of cleaning energy is intensified, and efforts to reduce greenhouse gas such as carbon dioxide. Measurement indicators of electrification level and energy efficiency Measurement of electrification levels, electricity, power generation can account for three indicators such as one energy specific gravity and electrical energy accounted for end energy. Solar energy has no pollution in the environment. It is of great significance for ecological no damage, good environmental benefits and ecological benefits. It is of great significance for human society's sustainable development. Solar thermal utilizatio...
