In the simulations polynomial functions were used to describe the temperature dependency of the thermal properties of the cylinder interior, which is a complex system composed by a solid porous material, a solvent and acetylene dissolved in it. Model equations covered heat conduction in the cylinder interior and at its walls, while the fire surrounding the cylinder was simulated by solving the coupled heat transfer and the momentum equation. Results of the calculations and the effects of some model parameters are discussed.
