文摘
- •
An unsteady-state finite-difference model of cold-region tunnel temperature fields is presented.
- •
The coupled convection–conduction problem is considered.
- •
Effects of mechanical ventilation and train-induced winds on the tunnel temperature distribution are studied.
- •
In situ observed frozen lengths in a cold-region railway tunnel are compared with the calculated results.
