Abstract:This study examined the risk of vertical fire spread on exterior walls subjected to flame ejection by measuring temperature and heat flux during real-scale fire experiments. The fire experiment was conducted in a mock-up measuring 2.4(L) × 3.6(W) × 2.4(H) m. Wood cribs were used as the combustible material, and heptane as the initial ignition source. The mock-up featured two singular openings of different dimensions, 2.2(L) × 2.0(H) m (#1) and 2.2(L) × 1.0(H) m (#2), on its front side. Temperature and heat flu… Show more
