| Abstract: | Simulates the smoke movement in atrium fire by using large eddy simulation. Obtains some details of the smoke spreading, the smoke velocity filed and temperature field, and the ceiling jet velocity and temperature. The results indicate that large eddy simulation can accurately predict smoke movement, and be used as a reference for the fire protection design of buildings with atria. |
