不同密封材料人工硐室储气响应研究
Research on air storage response of lined rock caverns with different sealing materials
摘要
Abstract
To investigate the temperature characteristics of compressed air in lined rock cavern(LRC)under different sealing materials and its influencing factors,a coupled computational fluid dynamics(CFD)model of the LRC gas storage was established.The thermodynamic response characteristics of air during the first charge-discharge process and long-term operation of the LRC storage under different sealing materials were systematically analyzed.Sensitivity analysis was carried out for the factors affecting the air temperature change in the cavern,including gas injection temperature,gas injection rate,and upper limit of operating pressure.The results show that the lower the thermal conductivity of the sealing material,the higher the temperature in the cavern after the first gas injection.Moreover,the spatial distribution characteristics of temperature are closely related to the flow field distribution.Significant local high temperatures occur near the gas injection ports,which are prone to causing uneven thermal stress on the sealing and lining structures.Among the three types of sealing materials,the gas injection temperature has the most significant impact on the maximum average temperature,and the lower the thermal conductivity of the sealing material,the more pronounced this impact becomes.关键词
