Abstract:
Objective During the operation of artificial caverns, the gas distribution method has a significant impact on the pressure, temperature, and other thermodynamic properties of the gas. These changes in gas properties further affect the performance, safety, and stability of the caverns.
Method A transient three-dimensional CFD model of an underground artificial cavern featuring a tangential gas distribution method was established using Fluent. The study investigated the changes in the temperature, pressure, and other thermodynamic properties of the gas inside the cavern during the charging process, analyzing the influence of the tangential gas distribution on gas thermodynamic properties.
Result The results indicate that the tangential gas distribution method can optimize gas distribution, effectively control the gas temperature near the cavern wall to prevent local hot spots during cavern charging, and thereby improve the efficiency and safety of the CAES system.
Conclusion Compared to conventional gas distribution methods, tangential gas distribution shows certain advantages in preventing local hot spots during the charging process in artificial caverns.
