摘要：

The fire triggered by the leak of combustible gas is a serious threat to the public and firefighters. Backdraft is a special fire phenomenon in a limited-ventilation room. This paper reports preliminary numerical simulation of backdraft phenomenon observed in a reduced-scale experimental compartment which has different openings. A sub-grid scale model for partially premixed combustion was applied to simulate the backdraft phenomenon. The analysis was performed with a hybrid of Large Eddy Simulation (LES) and Reynolds-averaged Navier Stokes (RANS). The results from numerical simulation accord well with the experimental results, which means that the research method of numerical simulation is reasonable.
