RESEARCH ON HOT SURFACE IGNITION CHARACTERISTICS OF LEAKING FUEL IN SHIP ENGINE ROOM
ABSTRACT
Hot surface ignition is crucial in safety management of maritime industry. In present work, 3-D numerical simulations using FLUENT of ship engine room model and ignition process of a leaking marine fuel by a high temperature hot surface are carried out. The thermal mechanism and hot surface ignition characteristics are revealed. Meanwhile, effect of ventilation and wettability on influencing leaking fuel hot surface ignition process in ship engine room are further analyzed. Hot surface ignition process of evaporated fuel indicates different characteristics, such as ignition delay, stable combustion and extinguishing. The results suggest that the strengthen of ship engine room condition directly promotes liquid-flow and ignition of leaking fuel on hot surface.
