- •
The thermal conductivity of a fine-grained sand has been investigated.
- •
The measurements were carried out using a steady state divided bar method.
- •
The degree of saturation has a significant effect on the sand thermal conductivity.
- •
A selected prediction models were validated against the experimental results.
- •
A new empirical model based on water content and porosity has been proposed.
