In order to control the smoke diffusing and prevent the damage to the people, the smoke temperature was researched. In high-rise building fires, the most immediate threat to passengers’ life is not the direct exposure to fire but the smoke inhalation because it contains hot air and toxic gases, so it has positive meaning to find the rules of the smoke temperature distribution. The variable rule of smoke temperature field distribution in passages of high-rise building was the foundation of fire fighting project. Heat-transfer process between smoke and building walls was analyzed by establishing difference equation of heat balance and diffusion process between smoke and transverse passage of high-rise building was analyzed by mathematical model of air mixed with smoke. The variable rule of smoke temperature, diffusion time and length of exit passageway was analyzed by case. Smoke temperature variation in smoke diffusion process was affected mainly by generation quantity of smoke and less affected by heat-transfer process between smoke and building walls.
Key words: Computational simulation, fire smoke, high-rise building, temperature, , ,
