Abstract
This work developed a dynamic 3D simulation of saline caves discharge used for a compressed air storage system (CAES). Initially, a reduced scale model of the problem in a discharge cycle is solved to validation. It is used real data provided by the Huntorf plant in Germany. The validation results obtained initially showed a relative error of 8% for pressure and 97% for temperature compared to the proportional results available in previous studies. As a way to investigate the causes of the high temperature error, a new simulation was performed applying the three-dimensional model data in scale to a validated analytical dynamic discharge model, using the same parameters in both. Thus the relative difference passed to 2% in relation to the pressure and 0.5% of the temperature. Obtaining a valid three-dimensional model for a CAES system has advantages over the analytical ones, such as obtaining the different temperatures inside the cave. For the application of this model, future studies are needed to correct temperature differences between the scale model and the real model.
