Gas Dispersion Modeling

Involvement of flammable or toxic materials in a process plant causes the risk of accidents. Hazard analysis and risk-based management are important to prevent escalation of dangerous event. Due to ill-defined leakage conditions, there are a few areas of uncertainty which lead to difficulty in po...
