dc.description.abstract | The validation of the Aerial Drop Model consisted of the comparison of computed ground patterns with experimentaldata fromaset ofreal-scale droptestsusingwater anda widerange offire retardant viscosities.Results were analysed in terms of pattern length and area. A total of 78% of the computed line lengths per coverage level were within a 10% error, with an average normalised mean squared error of 0.01 and a Pearson correlation coefficient above 0.9. In all cases,nearly90%oftheresultswerewithinafactorof2ofobservations.Theaccuracyofthesimulationsshowednostrong relation with the viscosity, although better results were obtained in the range from 700 to 1100cP. In general, the model produced a good representation of the spatial distribution of the agent for various coverage levels and its accuracy was, in fact,within thestatistical uncertaintyofthecup-and-gridsampling method.Thegoodperformanceobtaineddemonstrates that this tool, for the tested range of drop conditions, fulfils the requirements for use in the optimisation of firefighting operations, as a complementary method to real-scale drop testing, and in firefighter training activities. | pt_PT |
