WUIWATCH Laboratory experiments on firebrands and smoke related to house vulnerability
In July 2015 wuiwatch partners ADAI-CEIF have completed the design and installation of a dedicated infrastructure for the study of house vulnerability regarding the entrance of firebrands (flying embers) and smoke. The infrastructure consists of a 75% scale complete room with windows and doors, fully equipped with sensors and which is inserted in the wind tunnel of LEIF laboratory and which is exposed to a flow of burning firebrands generated by a dedicated device (the ‘micro dragon’). Monitoring is performed by visual and IR video cameras and a particle tracing software. CEIF-LEIF team has conducted a long list of experiments underlining the importance of open or closed doors inside the house as a relevant factor for the effective inflow of external smoke and firebrands. Full datasets, videos and pictures are available for a further detailed analysis to drive final conclusions. The results will be presented and published in the next wuiwatch workshop on house vulnerability which will be held in Portugal late November 2014.
