Abstract：
Develops an unsteady mathematical model of ventilation system for the corridor in dam. Numerically simulates the coupled heat transfer between airflow and rock with FLUENT software, predicts their temperature fields, and analyses the cooling effect of the corridor on airflow. Compares the simulation result with the theoretical calculation result and the test data and finds that they are in good agreement.
