Timber beam in virtual furnace

Popis výsledku v původním jazyce

The virtual furnace takes advantage of great possibilities of computational fluid dynamics code Fire Dynamics Simulator. The model is based on an accurate representation of a real fire furnace of fire laboratory PAVUS a.s. located in the Czech Republic. It includes geometry of the real furnace, material properties of the furnace linings, burners, ventilation conditions and tested elements. Gas temperature calculated in the virtual furnace is validated to temperatures measured during a fire test. The paper presents a coupled numerical model for prediction the fire resistance of elements in a horizontal furnace. The presented part lies in a virtual furnace which simulates temperature environment around tested elements in the furnace. Comparison of results show good agreement in the case when burning of timber is included in the numerical model. A contribution of burning of timber beams to temperature increase inside the furnace is graphically demonstrated. The temperature fields calculated in the virtual furnace are then passed to finite element model created in software Atena Science. In this model heat transfer into the timber beam is solved. Temperatures calculated inside the timber beam are compared to measured values from the fire test.
