Pool fires with different ullage heights are a common type of fire accident. A series of gasoline pool fire ex- periments with two sizes (D = 40 cm, 60 cm) and six ullage heights (h = 0, 0.2D, 0.4D, 0.6D, 0.8D, 1.0D) are conducted. The burning process, axial temperature profile, radiative heat feedb ...

Preventing fire spread between tanks is essential for fuel storage facilities. Therefore, ignition behavior of tank fires with different ullage heights and tank spacings was studied, focusing on the ignition process, ignition mechanism and radiative heat transfer. A series of experiments with n-hept ...

Thin-layer boilover of large-scale diesel pool fires at sub-atmospheric pressure

As thin-layer burning of fuels on water are often followed by thin-layer boilover fires, particularly during the firefighting process, an experimental and numerical study was undertaken to address key aspects of such fires, especially in plateau areas (i.e., sub-atmospheric pressure). In the thin-la ...

Effects of crosswind and ullage height on internal temperature distributions of tank fires
Jinlong Zhao, Shaohua Zhang, Zhenqi Hu, Grunde Jomaas, Jianping Zhang, Huiling Jiang, Zhian Huang
Izvirni znanstveni članek
Oznake: požari v rezervoarjih;stranski veter;višina prostora nad tekočino;napoved temperature;globoko učenje;tank fires;crosswind;ullage height;temperature prediction;deep learning;
Tank fires are typically characterized by intense combustion, high temperatures, and strong thermal radiation. The coupled effect of crosswind and tank ullage height leads to complex evolution of internal burning param- eters. Existing monitoring methods are mainly limited to external measurements, ...

Evaporation and piloted ignition in porous media soaked with heptane
Hanchao Ma, Weiguang Kong, Grunde Jomaas, Benedetta Anna De Liso, Ernesto Salzano, Hong Huang, Jinlong Zhao
Izvirni znanstveni članek
Oznake: porozne snovi;vnetljive tekočine;izparevanje;trajni vžig;modeliranje;porous media;flammable liquids;evaporation;sustained ignition;modeling;
In incidents involving liquid fuel spills, the application of porous media such as sand is widely regarded as an efficient and safe mitigation measure. However, the effectiveness of this approach in preventing ignition has not been thoroughly investigated. This study investigated the evaporation and ...
