摘要

目的

在人工硐室工作过程中，布气方式对气体的压力及温度等热力学特性的变化有较大影响，而气体的特性变化会进一步影响硐室的性能及安全稳定运行。

方法

运用Fluent进行数值模拟的研究方法，将采用切圆布气方式的地下人工硐室作为研究对象，建立了人工硐室瞬态三维模型，研究了人工硐室在充气过程中内部气体的温度、压力等热力学特性的变化规律，分析了切圆布气方式对气体热力学特性的影响。

结果

结果表明，切圆布气方式能够优化气体分布，有效控制硐室靠近壁面的气体温度，防止硐室充气过程中出现局部高温，提升压缩空气储能系统的效率和安全性。

结论

切圆布气相比于常规布气方式，在防止人工硐室充气过程出现局部高温方面存在一定优势。

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

alyzing 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.
