Implementation of a Physical Flame Spread Model in the SOFIE CFD Model. Brandforsk Project 307-971

摘要

This report describes the work performed by SP within a joined project between Lund University and SP. The project, called 'Development of Engineering Tools for the Prediction of Flame Spread,' increased the knowledge of flame spread modeling both with respect to thermal flame spread models and pyrolysis models. The implementation of a physical flame spread model developed by Yan inside the SOFIE CFD model has been described. Moreover an extensive sensitivity study of the pyrolysis model has been performed and a vertical stand-alone flame spread model has been developed using this pyrolysis model. Both items were performed as validation work for the pyrolysis model. The possibility of the use of a flame spread model inside SOFIE will enlarge the future application areas for CFD modeling within fire research and fire engineering. For this reason some future feasibility studies and guidelines are given in the conclusions of the report.
