| Abstract: | During a high rise building fire, the rule of change in smoke temperature is the basis of fire engineering design. Based on the element's heat balance difference equation educed from one dimensional heat conduction equation and the technology of control volume, the temperature of smoke during a high rise building fire was calculated. The research provided the fundamental data for the design of smoke prevention, exclusion and personnel evacuation systems. |
