摘要
Abstract
To study the flow field characteristics of Highway tunnel by roadway construction ventilation, three-dimensional models is built and simulated numerically with the software Fluent based on Liangfengao tunnel in Guizhou province. By studying on the flow field features near the pedestrian cross channel and dealers cross channel with the tunnel in same velocity conditions, analyzing the specific features of the flow field distribution. The simulation results show that the flow field distribution is substantially same near the pedestrian cross channel and dealers cross channel;The velocity in cross-channel is about 10%in the tunnel;The cross-channel velocity distribution and total pressure distribution are consistent Substantially of different velocity;The flow field is relative stability on both sides, so wind volume and pollutants won’t be exchanged.关键词
