    • Abstract
  • Based on the ADINA software, a three-dimensional temperature field model for PE pipes, anchors and soils with the characteristics of coupling of fluid and solid is established to analyze the heat transfer performance of energy anchors. Since the pipe fluid speed, soil properties and filled materials play important roles in the heat transfer performance of the energy anchors and the trend of soil temperature field surrounding the anchor holes, the model provides an effective way to get the best fluid speed and the temperature of supply water. The proposed model provides a theoretical basis for the parameter optimization of engineering design.
