摘要：

Three-dimensional and two-dimensional simulation tools were made and time-dependent circulations of water in large scale artificial basins were examined for thermal energy storage. Natural and forced convection with advection-diffusion energy transport cause these circulations. This paper focuses on basins filled with porous media. The modified Boussinesq equations for porous media and the finite element method were used. The time integrator for the transport equation is explicit for advection and implicit for diffusion, second-order accurate and of the streamline upwind type. Continuous experimental data from the Stuttgart artificial aquifer field test site has been collected for several years. These measurements were compared to many finite element simulation results. Later the simulation tools were applied and two- and three-dimensional basin geometries of up to 20 000 m(3) volume were studied.
