| Abstract: | The heat transfer of groundwater heat source wells in saturated soil is analyzed with Darcy's law.The coupled thermal conduction and groundwater advection model is also established.Then the influence of seepage flow velocities on the temperature of heat source wells is studied with or without groundwater advection.Finally,the COMSOL Multiphysics software is applied to numerical simulation.Example shows that this model has good applicability and it provides theoretical support for system optimal design and r... |
