Further Validation of Fire Dynamics Simulator Using Smoke Management Studies

Further validation of Fire Dynamics Simulator (FDS) developed by NIST (USA) is performed using four smoke filling scenarios reported in the literature. Careful comparison is made to experimental data available for those scenarios. Performance of the code was found to vary considerably with complexity of scenario (e.g. geometry). While giving very reasonable results for a number of cases, average deviation from experimental values in smokefilling rates and temperature predictions were above limits claimed by developers. The study emphasizes need for further development and extensive validation of CFD codes used by fire engineering practitioners.
