The main goal of this thesis is to contribute in the development of the FDS code program by facilitating some new reacting and non-reacting cases with different behaviours, for instance: changing thickness along time, charring and non-charring materials, in order to find similarities and discrepancies between the two programs (FDS and GPYRO). In the one hand, the non-reacting cases have been proved to be similar independently of the program used. The comparison stablished will be simple as it will only be focused on one feature: the temperature of certain significant point of the samples. On the other hand, the reacting case are the main challenge of this thesis, as these cases are the most complete ones, where all the theoretical concepts of the thesis will be put into practice. Therefore the comparison stablished will be much deeper in this chapter and it will be focused on the three following main features: temperature profile of some critic points, the mass loss rate and the thickness change with its slope if it was necessary. The objective will be to try to find as many different test cases as possible, including a wide variety of boundary conditions as well as different chemical reactive parameters, in order to see clear peculiarities or behaviours that facilitate the improvement and the study of new ways to make of FDS a better and more reliable code program in the field of pyrolysis modelling.
