Project aims to create a publicly available data set to be used for validation of the CFD based fire models with an emphasis on validating the solid state pyrolysis as a one of the key components of complex process of the solid materials burning. Laboratory and real scale fire experiments publicly available within the fire research community are not sufficiently instrumented and documented to be used as a validation data set for CFD fire models. Project focuses on identifying quantities to be measured that describes both the solid state such temperature as mass loss rate as well as the thermal feedback from surroundings in a cone calorimeter and furniture calorimeter scale. Repeatability of this highly dynamic and unpredictable phenomena will be addressed to provide high fidelity data.
