Abstract
Aquifer thermal energy storage system (ATES) for long term storing of excess thermal energy for future use is under research focus for quite some time. The present study is concerned about presenting a one dimensional numerical model of such a system with a porous aquifer with block heterogeneities, where hot water in injected through a single injection well into the porous aquifer and the movement of the hot water thermal front generated due to the injection is investigated. The numerical modeling is performed using multiphysics software COMSOL. The model is developed first for the general case considering convective and conductive modes of heat transport and a time varying pulse type injection rate and then for simpler case considering injection rate constant. Results for another simple model for a homogeneous aquifer are also presented in order to compare and validate it with an analytical model derived here. Assessment of the influence of some parameters involved in the heat transport phenomenon in porous media is performed at last.
