VALIDATION OF A VIRTUAL ROOM CORNER FIRE TEST WITH SPRUCE MEMBERS AND THE DEVELOPMENT OF THE CHAR LAYER

Popis výsledku v původním jazyce

This article presents the validation of the Computational Fluid Dynamics (CFD) model of the Room Corner Test (RCT). In the RCT experiment, a natural fire with two columns and one beam is studied. The specimens were made of spruce wood. The CFD model integrates the calculation of complex pyrolysis. The Fire Dynamics Simulator (FDS) was used, and the input data was created. In the experience of previous models, emphasis was placed on the selection of input data for the pyrolysis model. Various pyrolysis models with a single reaction pattern or with parallel reactions were studied in a numerical simulation. This work provides insight for advanced modelling of wood samples in a natural fire, taking into consideration the pyrolysis model. The CFD model with pyrolysis, considering massive specimens, has not previously been adequately validated and presented. To show the applicability of the model, the development of the char layer of the timber column most exposed to fire is presented.
