Numerical simulation on dense gas dispersion and fire characteristics after liquefied natural gas release

Abstract

This PhD dissertation mainly studies the prediction, simulation and mitigation methods of the two main hazards in LNG (Liquefied Natural Gas) industry, LNG vapor dense gas dispersion and LNG fire radiation, respectively. For industrial application purpose, integral model and solid flame model of vapor dispersion and fire radiation, respectively are researched and suggested for using. For complicated scenarios or mitigation measures applied, CFD (Computational Fluid Dynamics) models are studies on the two main accidents.
