CFD Modelling of LPG Dispersion in a Road Environment

the properties of the leakage. Furthermore, the presence of vehicles on the road may significantly affect the dispersion and concentration of the cloud and may cause partial confinement or obstruction of the cloud, which could potentially become a source of dangerous gas explosions on the road. This paper presents a numerical study of dispersion of LPG in a road environment following an unintended leakage from a road tanker. The work was conducted using the computational fluid dynamics (CFD) code FLACS-CFD. The purpose was to quantify the extension of the gas cloud within the flammability limits for different leak properties, wind conditions, and traffic layout. For each case, an equivalent gas cloud with a regular shape and stoichiometric concentration was determined using the Q9 cloud model. Based on the results, recommendations for the choice of equivalent gas volume for different standard scenarios are presented.
