Abstract
Natural gas is most commonly transported by pipeline. However, leaks sometimes occur during transport, often leading to jet fires that cause substantial economic damage and property damage. It is therefore crucial to improve the efficiency of jet fire suppression. This paper focuses on the change of flame morphology of horizontal jet fires under different boundary conditions (acoustic pressure, frequency and jet exit velocity) and experimentally analyses the horizontal, vertical and trajectory length variation laws of the flame. Then a prediction model relating the horizontal length, vertical length and trajectory length of the horizontal jet flame under the action of acoustic waves is established.
