The wind effects on the wind flame spread across the exterior wall of the high-rise building were studied by the numerical methods.The simulation was focused on the top 5 floors of a hotel,and the max fire power is 2 MW and 6 MW separately.The distribution of temperature and velocity vector of windows plume was obtained under different scenarios.The results showed that high wind speed will change the window flame spread direction and make the room inclined above the fire room more danger,especially the room at the same floor adjacent to the fire room.Special passive fire protection measures should be taken under these kinds of conditions.
