The proposed model has three principal innovative advantages over classical Lagrangian approach: i) Speed: Fast calculation of the spray anywhere; ii) Description of the spray in the phase space, which turns the description of the spray into a time-independent, enabling compact, fast, and useful reconstruction of the spray; iii) Description of the spray as a set of 2D spray dispersion fields allowing considerable simplification of the spray field analysis. As results, a 2D visualization of the spray (volume flux), and an example of volume flux into a surface are reported.EnglishLACCEI Licensehttps://laccei.org/blog/copyright-laccei-papers/SprinklerFire-ProtectionBIMArticle
