Overview

Experimental measurements reveal thermal behavior in soils, indicating phase changes impact energy transfer.

Key Points

  • The aim is to investigate how soil properties change during freeze-thaw cycles and their effects on energy exchange.
  • Conducted experiments on sand, silt, and clay soils across a temperature range of -15 °C to 20 °C.
  • Examined the effects of saturation, organic content, and salinity on thermal parameters.
  • Quantified both vertical and lateral conductive heat transfer components.
  • Frozen soils showed lower emissivity compared to thawed soils, with nonlinear transitions at phase changes.
  • Thermal conductivity increased significantly in the frozen state due to enhanced grain contacts.
  • Neglecting lateral heat flux underestimated total conductive energy transfer by up to 31.65%.
