摘要： 通过实地调研得到典型商业厨房物理模型。设置8种工况，利用CFD模拟商业厨房不同火灾事故场景下的烟气、温度、能见度等参数的变化规律，得到不同火灾事故场景的演化特点。分析结果可知，商业厨房发生火灾约30~40 s后，厨房内2 m高度处截面的能见度降到10 m以下，影响人员疏散；发生火灾约50~150 s后，门口1.8 m高度处测点温度达到60 ℃，影响人员的生命安全。

Abstract: Through the field research, the typical commercial kitchen structure model was obtained. Eight working conditions were set up to simulate the changing rules of smoke, temperature, visibility and other parameters in different fire accident scenarios of commercial kitchen by CFD, and the evolution characteristics of different fire accident scenarios were obtained.The analysis results showed that the visibility of the section at 2 m height in the commercial kitchen decreases to less than 10 m after 30~40 s of fire, which affects the evacuation of personnel. After 50~150 s of fire, the temperature of the measuring point at 1.8 m height near the door reaches 60 ℃, which affects the life safety of personnel.
