Numerical Investigation of Temperature Distribution in a Fire Resistance Test Furnace

Fire is one of the most important securities of life issue in crowded life spaces. In order to determine whether the construction materials provide the necessities in the standard, conditions during a fire incident should be simulated and materials need to be tested in this simulated environment. Fire resistance test furnaces are used in determining the fire resistance of a material. In this study, according to the general rules for fire resistance experiments defined in TS EN 1363-1 standard, a fire resistance test furnace is designed three dimensionally and computational fluid dynamics analysis of the fire test furnace is done with ANSYS Fluent program in order to evaluate and determine the temperature distribution inside the fire test furnace. The governing equations for mass, momentum and energy were solved for the three dimensional unsteady incompressible flow, with radiative heat transfer and turbulence model. It was found that temperature distribution inside furnace plays crucial role on volume mean temperature of furnace
