N2 - This paper is to investigate the smoke flow temperature beneath the ceiling in an atrium-style subway station. Numerical simulations were carried out in a full-scale model to study the temperature profile beneath the ceiling by considering different fire source locations. Results show that the maximum smoke temperature beneath the ceiling can be predicted using the three models developed by Alpert, Heskestad and McCaffrey. The choice of the most suitable model depends on the fire source location. For the longitudinal temperature distribution along the ceiling, if the disturbance region is far away from the fire source, the temperature profile can be well correlated by the Li's model. However, if the disturbance region is close to the fire source, the models proposed by Li and He should be used together. The temperature profile beneath the ceiling in this kind of subway station with different fire source locations can be obtained by the combination of these models.
