Modeling and Simulation of Heat and Moisture Transfer of the Geothermal Borehole
According to the mass conservation and energy conservation theorem,established a finite length cylindrical surface heat and moisture transfer model which base on the cylindrical heat transfer model of vertical ground source heat exchanger for soil layer around geothermal borehole.Using COMSOL multi-physics coupling analysis software,simulated the non-steady-state heat and moisture transfer for soil layers of heat exchanger under summer operating conditions,and analyzed the influence in temperature field and moisture field of soil layers exerted by the heat and moisture transfer under different soil thermal properties and initial moisture contents.At last there is verification by FLUENT software.
