Aerothermodynamic Calculation Research on Compressed Air Energy Storage of Artificial Cavern
摘要
Abstract
The temperature change of the air inside the artificial cavern under the condition of inflation and extraction is the basic content of analyzing the working characteristics of the artificial cavern.Assuming that the heat conduction in the tunnel wall is an infinitely thick cylindrical problem,considering the convective heat transfer between the tunnel wall and the air,a coupled analytical calculation method for the thermodynamic process of the air inside the cavern and the heat conduction process in the cavern wall is proposed.A comparison was made between the results of an engineering example between numerical method and this analytical method,and the results were in good agreement.The results indicate that under the standard inflation and extraction cycle,there is a significant change in the air temperature inside the cavern.The temperature of the steel sealing layer changes with the temperature of the air,and the amplitude is slightly smaller than that of the air.There is a convective heat transfer process between the steel sealing layer and the air inside the cavern.The temperature variation in the concrete lining decreases rapidly with distance.关键词
