Science Pumped Abstraction-Artificial Recharge tool and Pumped Abstraction-Natural Recharge tool What? The new tool LoCAL-PAAR (Pumped Abstraction - Artificial Recharge) gathers together the flow skills of EPANET with the thermal skills of Rodriguez and Diaz model under a spread sheet that runs a macro code. The tool allows to estimate the outcoming temperature of the flow is crucial for geothermal aplications of the mine water. LoCAL PANR is built in an excel workbook that interacts with the users by means of 4 sheets which can be activated or deactivated depending on the options selected. This tool, which has been called LoCAL PANR (Pumped abstraction - Natural recharge), constitutes a heat transfer calculator addressed for scenarios of an underground mine whose water is being pumped with a geothermal purpose. At these scenarios, the heat is extracted from or dumped into the pumped water and consecutively, the water is disposed of to a surface water. How? LoCAL - PAAR fits for scenarios where, after the reinjection, the minewater flows through a network of galleries exchanging heat with the surrounding rock mass. The aim is to calculate the temperature of the mine water at the abstraction point which will strongly depend on the itinerary and the dynamics of the fluid. PANR (Pumped abstraction - Natural recharge) is a heat transfer calculator addressed for the scenarios of an underground mine whose water is pumped with a geothermal purpose. The heat is extracted from or dumped into the pumped water and consecutively, the water is disposed of to a surface water. At this scenario, there is no deliberate reinjection of thermally spent water. PAAR.xlsm PANR.zip
