Computer Simulation of the Motion of Heat Flow Induced by the Fire in the Long-Scale Tunnel

[摘要] References(9)In order to characterize the motion of the heat flow induced by fire in a real large-scale tunnel as well as the transport of the toxic gases, experimental and theoretical analysis the motion of the heat flow were investigated in a long-scale model tunnel. The computer simulation on the heat flow was conducted by using the Boussinesq approximation and Navier-Stokes' type formula as the viscous heat-conducting incompressible fluid. After recognition of a good correspondence on the heat flow properties between the simulated and experimental results, the computer simulation was scaled up by three times the length of the model tunnel. The life hazard of passengers was also discussed on the basis of the predicted CO gas concentration in the under-layer.
