Abstract

Aiming at the permeability of flexible sealing layer in artificial cavern for compressed air energy storage, the engineering application cases of flexible materials as sealing layers are sorted out. The current research progress in experimental research, theoretical analysis and numerical simulation in this field is expounded, and the advantages and disadvantages of each research method are analyzed. On this basis, the future research direction in this field is prospected. It is believed that in the future, key variables such as air pressure, temperature, tension state and cycle times should be comprehensively considered in the penetration test to reveal the penetration law of flexible materials. At the same time, the penetration evolution model is constructed and numerical calculation is introduced to further explore the multi-field coupling response characteristics of flexible sealing layer.
