In recent years

it has been a hot topic that the fire of high-rise building caused by burning of thermal insulation material on the exterior wall. The fires often cause heavy loss of people’s life and property. To explore fire spreading law of insulation layer of high-rise residential building

several typical parameters

such as heat release rate

CO volume fraction

temperature and flow velocity distribution in high-rise buildings were studied in details. The effect of outdoor wind speed and direction on fire development variation was considered and analyzed in this paper by using fire dynamics software FDS. A couple of numerical simulation experiments were conducted and fire development situation of thermal insulation layer on the external wall under outdoor wind conditions was researched as well. The results show that outdoor wind has a greater impact on the fire heat release rate

CO volume fraction

air temperature and flow velocity. The conclusions drawn by this research will be significant for the fire protection design and construction of the energy-saving buildings in the future.
