Numerical Simulation for Indoor Fire Impact under Various Ventilation Conditions
Ventilation influences Oxygen, heat flow and smoke situation needed during combustion and thereby, influences fire development indoors. This paper simulates indoor fire process utilizing FDS software. It studies the impacts of indoor combustion condition under various ventilations and further more, analyzes the shortage of combustion model utilizing FDS. What we get as result is combustion power of stabilization period presents direct ratio with ventilation area, and so is opening height with burning power. What is more, the impact of opening height for ceiling smoke temperature is obvious. To provide building fire prevention design evidence via finding out the critical state of ventilation control and fuel control. Numerical simulation result presents that the ventilation factor of stable combustion speed which no more linearly change along with ventilation factor is 3.97 m5/2.
