摘要: Abstract This paper investigates the axial temperature profiles in buoyant plume of rectangular source fuel jet fires. Experiments are carried out this work by nozzles with aspect ratio (width/length, W / L ) ranged from 1:1 (axi-symmetrical) to 1:71 (linear) Hefei city (100.8 kPa) and Lhasa (64.3 kPa). The profile is theoretically deduced for different dimensions heat release rates, based on conservation Froude number (momentum/buoyancy) where its dependency initial momentum then correlated experimental data. previous classic correlation established Quintiere extended fires including effect as well burner. proposed also further special sub-atmospheric pressure condition (Lhasa, 64.3 kPa).
