Near-Field Leakage and Diffusion Characteristics of Hazardous and Noxious Substance

Abstract

Because HNS (Hazardous and Noxious Substance) leakage causes huge casualty and environmental pollution, it is crucial to cope with HNS leakage accidents at the early stage, subsequently requiring accurate predictions of diffusion pathway and detailed understandings of diffusion characteristics. Thus, the present study aims to investigate numerically HNS (Styrene, floating HNS) leakage and diffusion behaviors when HSN spill occurs. Especially, much emphasis is on near-field characteristics which can be substantially affected by the crack position and the stored condition of HNS according to various risk scenarios.
