Based on pilot studiesSimulation of vertical fire characteristics of cavity curtain wall insulation system
In this paper,the vertical combustion of the cavity curtain wall insulation system is analyzed,and the temperature field distribution and flame propagation law are studied.By using FDS soft-ware to establish a relevant model for vertical fire propagation simulation,and comparing and ana-lyzing the results with the experimental research results,it is found that the simulation results are in good agreement with the test results,and the simulation can be applied to study the vertical combustion of cavities under more working conditions.In addition,the simulation results show that the combustion temperature of the insulation material inside the cavity can reach about 850℃,which can ignite the aluminum-plastic panel curtain wall,which has a great threat,which will increase the air circulation inside the cavity and increase the risk of fire spread.
