A high-temperature supercritical carbon dioxide gas jet erosion test device

Abstract

The application discloses a high-temperature supercritical carbon dioxide gas jet erosion test device, and relates to the field of high-temperature and high-pressure material service and test, which comprises a closed dynamic circulation loop and a gas supply system for supplying gas to the closed dynamic circulation loop; the closed dynamic circulation loop comprises a jet erosion test section, a carbon dioxide storage tank, a booster pump and a heater group; the jet erosion test section comprises a high-temperature and high-pressure carbon dioxide storage tank and a high-temperature and high-pressure container; the high-temperature and high-pressure container is provided with a jet nozzle and a sample table, the jet nozzle is connected with a gas inlet of the high-temperature and high-pressure container, and is used for spraying high-pressure gas flow towards a sample on the sample table; the outlet of the carbon dioxide storage tank is connected with the booster pump, the heater group and the high-temperature and high-pressure carbon dioxide storage tank in sequence. By adopting the scheme, a general erosion evaluation platform for realizing high-temperature and high-pressure stable jet, nozzle momentum / kinetic energy flux closed loop maintenance and supporting critical flow steady state can be achieved through the circulation loop.
