How much energy is stored per unit pile?
Quantitatively, the daily average rate of energy storage per unit pile length reaches about 200 W/m for the case in saturated soil with turbulent flowrate and high-level radiation. This is almost 4 times that in the dry soil. Under low-level radiation, it is about 60 W/m.
How many cycles of energy storage are maintained in a pile-soil system?
In addition, the model domain of the energy pile-soil system has limited dimensions and thus only five cycles of energy storage were maintained for each test. These factors affect the results quantitatively, while they should not invalidate the fair comparison between different tests.
