“…For that arrangement, they found that the average burning rate achieved a maximum at −50°, dropping off slightly to −90°, and much more steadily to +90°. They and others 1–7 more thoroughly examined the purely horizontal or vertical orientations. Blackshear and Murty 1,2 explained their results through the B number and the heat transfer coefficient.…”

Burning on flat plates was studied at various orientations with respect to gravity. Flat wicks of ceramic (Kaowool PM) board (10 cm wide and 1-10 cm long) were saturated with methanol or ethanol. Steady flames were obtained that ranged from boundary layer flames to plume-type burning. The onset of unsteady flow and transition to turbulence commenced at Grashof numbers of 10 6-10 7 , increasing with decreasing angle (toward underside burning). The average burning rate per unit area was recorded along with the flame location. Experiments on polymethylmethacrylate were used for comparison with the liquid-wick results. The results roughly correlated with laminar pure convective theory, and improved results were indicated when the gravity term associated with the pressure gradient normal to the plate was included. Theoretical results by the integral method to reduce the partial differential equations to ordinary differential equations are presented.

“…The peak unit area heat release rate decreased with increasing diameter much like that for liquid pool fires [11] in the laminar range of burning. For pool fires, the rates increase with size for diameters between 0.3 and 1.0 m. This behavior was absent in Figure 11.…”

“…The Hypalon cable tests used packing arrangements ranging from loose (test 11) to extra tight (test 10). However, both tests 10 and 11 had burning rates of only about 0.1 kg/min with predominantly scorching rather than pyrolysis of the fire affected areas by the heptane ignition source.…”

Heat release rate characteristics of some combustible fuel sources in nuclear power plants

A major risk to a nuclear power plant is the possibility of serious fire. There is a need to know the heat release rate behavior of combustible fuels in the plant in order to help reduce the fire threat to these facilities. Heat release rate characteristics of cable tray fires and some of the associated potential external ignition sources are discussed. Existing correlations are given to determining the time to ignition and the subsequent heat release rate of spills and pools of flammable liquids. Approximate correlations are developed for heat release rate for trash fires as a function of fire size and for one particular cable tray array arrangement as a function of the type of cable. In addition, a scheme is given for calculating the heat release rate from wood fuel fires.
