Abstract:In order to investigate the diffusion law of CO gas in
the vicinity
of the tunnel boring face of the plateau long tunnel, to improve the
efficiency of tunnel smoke exhaust, and to derive the spatial-temporal
variation model of CO concentration for predicting the concentration
of CO at different times and in different cross sections under specific
environments, a CO diffusion model of a tunnel in Yunnan was established
by using Ansys Fluent Fluid Simulation Software, and the CO transport
characteristics under d… Show more
