Analysis of oil vapor diffusion after oil spill from tank group based on wind tunnel experiment and numerical simulation

The diffusion of oil vapor after oil spill from tank caused serious consequences. It is studied by combining wind tunnel experiment and numerical simulation. Results show that the higher the fire dike, the more oil vapor accumulates at the inner corner of fire dike; the explosion limit area is the largest when the oil spills in front of single tank on the windward side; concentration of multi-spills will superimpose to induce the presenting of multi-explosion limit areas. It can provide a reference for the research and development of the oil vapor traceability system and prevent explosion accidents in oil depots.
