非凝性气体对汽-气稳压器稳压的影响研究
Effect of Non-condensable Gas on Steam-gas Pressurizer
摘要
Abstract
T he heat and mass transfers in the interface of steam and liquid and condensa‐tion near the wall with non‐condensable gas were analyzed . A steam‐gas pressurizer model was developed ,the process of pressure transient in the pressurizer with the non‐condensable gas was investigated and the thermal‐hydraulic characteristics of a steam‐gas pressurizer were described .The calculation results were verified with the results from the MIT pressurizer experiment .The results show that the calculation accuracy using pressurizer model without non‐condensable gas is high ,the relative deviation is 0.8% and the peak pressure is 0.647 MPa .When the mass fraction of non‐condensable gas is from 0 to 20% ,the calculation accuracy decreases ,the maximum relative devia‐tion is 15.4% and the peak pressure is from 0.647 MPa to 1.02 MPa .It’s found that the non‐condensable gas plays an important role on the pressure response in the gas‐steam pressurizer .When the mass fraction and varieties of non‐condensable gas are different ,the pressure response in the pressurizer is significantly different .关键词
