Comparison of Shaft Fire Experiment and CFD Modelling

Popis výsledku v původním jazyce

The paper deals with the comparison of the first series of data, measured in a laboratory shaft model, with the results gained by mathematical modelling. From its cross-sectional dimensions, the half-scale shaft model corresponds to an apartment plumbingshaft in residential buildings and its height corresponds to approximately one and a half storeys. This situation is modelled by the Fire Dynamics Simulator (FDS) software using the principles of computational fluid dynamics (CFD). The measured and simulated results of temperature, total heat flux and flow velocity distributions for the tall narrow shaft space are presented. A mutual comparison between the laboratory measurements and the simulation is provided and discussed. The paper also presents a basic structural solution for plumbing shafts partially related to the experiment and problematic combustible utility cores, including plumbing shaft spaces in older prefabricated blocks of apartments in the Czech Republic.
