| Abstract: | In this paper,established the mathematical model of the process of thermal storage in the solar-ground concrete pile.It adopted finite element methods to numerically simulate the unsteady-state temperature field of concrete pile that around the underground vertical tube,given the calculated format of different boundary condition,analyzed the temperature variation rule of the concrete around heat exchanger.This paper provided reference basis of ascertain method about the bury depth of the vertical U-tube and the mix proportion of the concrete pile. |
