Laboratory experiment of fire spread between two informal settlement dwellings

Fire spread between informal settlement dwellings (ISD) is a primary concern for large scale settlements conflagrations. Globally, approximately one billion people live in and are exposed to these fires. This paper presents fire experiment two dwellings, built with ISO 9705 dimension as an approximation of ISD separated by 1 m. The development mechanisms within the ISDs were investigated benchmarked against independent single dwelling identical boundary conditions. Parameters, such mass loss rate fuel, total heat release rate, gas temperatures, wall roof velocity at openings measured, well external incident fluxes. A comparison double experimental results made. It was established that existence adjacent dwelling, which changes dynamics initial burning stage wood cribs delayed flashover more than 150 s (Dwelling 1). from perpendicular plane hypothetically concerned collapse or flame ejections cardboard linings, rather radiation heated metal wall, recorded fluxes 35, 20, 5 kW/m2, respectively. Due very thin-walls high conductivity natural leakage ISDs, current theories rates, shapes, conditions, based on thermally thick-walled do not replicate data well. new model accumulated energy, proposed this work conservatively under-predicts time ignition 9 % experiment.
