“…Finite-rate chemistry model and Eddy-Dissipation model are adopted to simulate the incineration. The mass fraction of substance Y i is calculated in the equation ( 1) and the reaction rate R i,r in the Eddy-Dissipation model is obtained from the smaller of the equations (2) [20].…”

The liquefied petroleum gas (LPG) cylinder incineration test is an important part of the cylinder periodic inspection to clean up the residual gas and ensure the safety of subsequent inspection items. However, the cylinder needs to be incinerated several times due to the uneven temperature distribution of the cylinder, leading to low incineration efficiency and waste of energy. In this study, a cylinder incineration test is experimentally investigated and a computational fluid dynamics (CFD) model is established to analyze the influence of incinerator structure parameters and cylinder types on the temperature uniformity of the cylinder. The results show that the temperature distribution of the middle surface of the cylinder is most uneven. With the increase of the burner nozzle diameter and the incinerator diameter, the standard deviation of temperature decreases at first and then increases, and the minimum is reached at 150 mm and 530 mm, respectively. The optimized design is found to have a better temperature uniformity of the cylinder with the burner nozzle angle of 0?. The optimal incinerator diameter for different types of LPG cylinders is different and decreases as the cylinder diameter decreases.

“…In order to obtain accurate results for the heat transfer at the wall, the use of a turbulence model able to solve the governing equation inside the boundary layer was preferred with respect to a wall function approach, adopted in previous studies (Bi et al, 2011;D'Aulisa et al, 2014aD'Aulisa et al, , 2014bLanducci et al, 2016;Zheng et al, 2013Zheng et al, , 2012. The turbulence model selected was the k-SST (Launder and Spalding, 1972).…”

The safety of small and medium LPG (liquefied petroleum gas) storage tanks in civil and industrial facilities when affected by forest fires in the framework of Wildland-Urban Inter-face (WUI) was investigated. Large scale experimental tests were carried to characterize the behavior of LPG tanks in case of distant source radiation caused by forest fires. A data set was obtained and used for the validation of a dedicated two-dimensional computational fluid dynamic (2D CFD) model for the analysis of pressure build-up in vessels exposed to different types of transient heat radiation, featuring different geometry types and operat-ing conditions. The combined experimental and numerical analysis allowed determining the critical exposure conditions for LPG vessels. Specific key performance indicators were defined and calculated on the basis of 2D CFD simulation results in order to derive conser-vative indications on failure conditions of LPG storage vessels induced by forest fires.
