Overview

CFD approach shows stable thermal stratification in underground thermal energy storage systems, indicating vital interactions between water and soil.

Key Points

  • The system maintains stable thermal stratification, with warmer water staying at the top while cooler water settles.
  • In the natural cooling scenario, the initial cooling rate impacts how long water remains above a certain temperature before equilibrium.
  • The submerged heat exchanger effectively extracts heat, with efficiency dependent on its dimensions and operational parameters.
  • The interaction between water and soil is crucial for heat extraction and storage, affecting the overall performance of the system.
