摘要
A mathematical model for smoke flow in high-rise building fires is established and a three-dimensional turbulence model of k-ε types is used in the simulation of smoke flow diffusion in transverse passageway of high-rise building fires. The temperature, velocity, environment and concentration fields of smoke in the 3rd, 4th and 8th floors are analyzed. Results show that the variations of temperature, velocity and concentration in the transverse passageway are related with the floors. The variations are more great and quick when the fire floor is further away from the neutral surface.
