Abstract: In order to further investigate the physical mechanism of the backdraft phenomenon in building fires, a simplified mathematical model is established based an energy balance equation, and its catastrophe mechanism is analyzed based on catastrophe theory, and the relationship between system control variables and fire conditions is studied. It is indicated that the backdraft phenomenon is a kind of typical catastrophe behavior, and of the common characteristics of catastrophe.
