Radiant heat from propane jet fires
Sonic propane jet fire experiments were carried out in absence of wind, with visible flame length ranging between 2.2 and 8.1 m. The thermal radiation intensity increased with the mass flow rate and the flame length. The net heat released was also computed and a correlation for the flame length as a function of Q is proposed. The surface emissive power and the fraction of heat irradiated were e...
متن کاملThermal and Geometrical Features of Jet Fires
In many severe accidents involving explosions or large fires, jet fires have been the first step of a domino effect sequence: a recent historical analysis has shown that among the accidents registered in the data bases, in approximately 50% of the cases in which it was a jet fire it caused another event with severe effects. However, the knowledge of jet fires essential features –behaviour, effe...
متن کاملJet Fires: a “Minor” Fire Hazard?
Jet fires have received only a rather reduced attention as compared to other types of fires; this is probably due to the fact that they are usually much smaller that fireballs, pool fires or tank fires. However, jet fires often occur in areas where there is other equipment and the probability of flames impinging on a pipe or a vessel can be high. Furthermore, due to the turbulence of the phenom...
متن کاملHeat Transfer Characteristics of Rowing Headgear with Radiant Heat Flow
INTRODUCTION Radiant heat gain to the head has recently been shown to affect sensation in human subjects (Buyan et al., 2006). However, only one published study has been conducted on the influence of radiant heat gain for sports headgear (Ishigaki et al., 2001). One could assume that reducing heat stress by shielding solar radiation using sports headgear would increase thermal comfort, and poss...
متن کاملRadiant Heat and Thermal Comfort in Vehicles
Infrared-reflective (IRR) treatment of automotive glass has been shown to reduce air temperature in vehicle cabins, thereby increasing fuel economy and occupant comfort. Its effect on radiant heat, however, may augment these benefits. In this study, the hypothesis that radiant heat affects subjective comfort ratings in a vehicle was tested. IRR films were systematically applied to the driver-si...
