COMPUTER SIMULATION OF FIRE TEST PARAMETERS FAÇADE HEAT INSULATING SYSTEM FOR FIRE SPREAD IN FIRE DYNAMICS SIMULATOR (FDS)

Abstract

This paper considers issues related to fire hazard of constructions of external walls fit with façade heat insulation and finished with rendering which is dependent on constructive solution of the heat insulating system and type of heat insulating material. Appropriate works aimed at use of “Fire Dynamics Simulator” (FDS) software for the computer simulation of fire spread across façade system surfaces and comparison of experimental and calculated data were analyzed. A number of full-scale fire tests were conducted of the external wall constructions fit with façade heat insulation and finished with rendering for fire spread while using 150 mm wide slabs fabricated of expanded polystyrene of “PSB-S-25” type as heat insulating material. Computer simulation 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 dwelling houses.
