Paper presented at the 6th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 30 June - 2 July, 2008.
A numerical code for the simulation of the one-dimensional
heat transfer through a commercially available gypsum board
exposed to fire is presented. A parametric study regarding the
physical properties of the gypsum is carried out. The
predictions obtained with the in-house developed code are in
good agreement with experimental data, when temperature
dependent physical properties are taken into account. The good
performance of gypsum boards under fire conditions, from the
fire safety point of view, due to the dehydration/calcination
process and the occurring energy absorption is pointed out by
the numerical results.
