  Abstract

This study presents a mathematical model based on a 3D unsteady-state convective-diffusion equation to predict chemical dispersion during and after continuous leak scenarios. This approach aims to determine whether continuous or instantaneous release calculations are valid for ongoing and post-leak dispersions. The proposed dispersion model was validated by comparing its results with those of a liquefied petroleum-gas (LPG) dispersion experiment. The accuracy and reliability of the model were evaluated by comparing the actual data with simulation results. The proposed model was more effective in predicting chemical dispersion in initial leakage scenarios than existing models. The mathematical model used in this study can serve as a valuable tool for predicting the dispersion pathway and concentration of chemicals in initial LPG leakage accidents, contributing to enhanced evacuation and rescue operations, and minimizing accident-related damage.
