Abstract :
In order to investigate the temperature field and flow field distributions in tunnel, a tunnel physical model containing an inner heat source was established by using computational fluid dynamics CFD simulation software Fluent 6.3. The finite volume method and SIMPLE algorithm were adopted to disperse and solve the governing equation. The simulations of the temperature field and flow field were carried out when the boundary temperature of the inner heat source was at 320 K and the ventilation velocity was 1m/s. The results show that there are temperature gradients along the longitudinal plane and the cross-sectional plane because hot air rises and cold air falls under the combined influence of the vents and the inner heat source.
