Abstract: The contribution presents part of activities that have been carried out for the preparation of the Conservation Plan of the Giancarlo De Carlo’s University Colleges of Urbino, funded by the Getty Foundation within the “Keeping it Modern” program in 2015. Starting form a comprehensive evaluation and understanding of the values that are represented in the complex, the Conservation Plan aims at establishing a “sustainable”management strategy, which means finding a “point of balance”between conservation and change, between an important cultural value, which has led to an international recognition, and the demands of everyday management.

N2 - Combustion experiments were performed for polyethylene (PE) in stagnation-point flow to investigate the fundamental characteristics of PE in high-temperature air combustion (HiTAC). Air diluted by nitrogen, water vapor, and carbon dioxide was tested as the oxidizer, and the oxidizer temperature was varied from 300K to 773K in order to investigate the effect of the dilution and temperature on the regression rate, the extinction limit, and the sooting limit of PE. The kinetic parameters of PE pyrolysis under the combustion conditions were estimated from the regression rate experimental data using a new method that combines experiments and numerical simulations. It was found that the previously reported kinetic parameters obtained with thermal gravimetric analysis (TGA) were much smaller than those obtained in this study. It was also found that the kinetic parameters varied when a different dilution gas was used, indicating that PE pyrolysis is affected by the composition of oxidizer.
