FDS simulation of fire spreading on facade heat insulating system

Abstract

The main purpose of this work was to determine the parameters of the fire test of the exterior wall construction with facade heat insulation and plaster to spread the fire by FDS simulation, to reproduce the real conditions of fire test and to verify the developed model by comparing the obtained data with experimental results. Satisfactory error was obtained when measuring temperatures experimentally and by computer simulation during experiments. An experimental study of the spread of fire on the surface of external walls with facade insulation and computer simulation of full-scale tests using computer methods of gas hydrodynamics. Using computer simulation of the parameters of the fire test of the facade insulation system for the spread of fire in the FDS environment, numerical and graphical indicators were obtained that characterize the process of occurrence, spread and development of fire by the surface of the facade insulation system. Computer modelling of fire dynamics using FDS numeric tool was implemented and results obtained were compared with experimental data in order to check possibility of use of appropriate software for the reproduction of real conditions of fires at residential buildings.
