PHASE CHANGE TWO-PHASE FLOW SIMULATION TEST DEVICE AND PHASE CHANGE TWO-PHASE FLOW SIMULATION TEST METHOD

摘要

PROBLEM TO BE SOLVED: To suitably test a sample dealing with phase change two-phase flow.SOLUTION: A phase change two-phase flow simulation test device comprises: a gas-liquid mixer 7 for producing a simulation gas-liquid two-phase flow by mixing high-density gas into a low-boiling point fluid; and a simulation gas-liquid two-phase flow supply pipe 14 for supplying a simulation gas-liquid two-phase flow to a sample 10. A simulation gas-liquid two-phase flow is treated by the sample 10 in a low-temperature and low pressure atmosphere while a comparison gas-liquid two-phase flow is treated in a high-temperature and high pressure atmosphere. The test temperature range adopted by the temperature in a low-temperature and low pressure atmosphere is lower than the temperature in a high-temperature and high pressure atmosphere. The physical property of the gas phase of the comparison gas-liquid two-phase flow in a high-temperature and high pressure atmosphere is substantially equal to the physical property of the high-density gas in a low-temperature and low pressure atmosphere. The boiling point of the low-boiling point fluid within the test pressure range is included within the test temperature range. Such a phase change two-phase flow simulation test device 1 can suitably test the sample 10 by changing phase of the modulation gas-liquid two-phase flow in the sample 10.
