Abstract
This article purpose is the development a thermodynamic model that simulates the performance of a Compressed Air Energy Storage System, during its charging stage. In this phase, the irreversibilities considered were due to the heat exchange between the compressor housing and the surrounding environment. The air storage tank was considered adiabatic though. The pressurizing stage was analyzed as a transient process, as a consequence of the variable inlet mass flow. Therefore, through the simulation the behavior of several variables involved in the process were assessed (e.g. pressure, temperature, compressor work and the irreversibilities). This analysis made it possible to quantify the amount of energy that can be stored in a reservoir and also the exergy destroyed during the air storage process.
