According to the invention, ship cabin jet fire combustion simulation experiments under the action of different angles and types of barrier wall surfaces can be realized; the platform can reveal and is not limited to a jet fire combustion kinetic parameter change rule under the effect of a marine engine room barrier wall surface and a jet fire plume behavior characteristic kinetic evolution mechanism under the change of factors such as a gas leakage aperture and rate, a jet angle, a hole-wall distance and the like.

Description

technical field [0001] The invention relates to the technical field of fire simulation, in particular to a gas jet fire experiment platform on the wall surface of a ship engine room barrier. Background technique [0002] With the increasingly stringent environmental protection requirements of IMO (International Maritime Organization) and various countries, new energy LNG (liquefied natural gas) powered ships have become the key development direction of the future shipping and shipping industry. However, the use of new energy LNG will bring new fire threats, and the leakage of gas fuel in the engine room can easily induce jet fires. The engine room, which is the heart of the whole ship, is equipped with facilities and equipment such as power equipment, electrical devices, pipelines, and marine oil tanks in a limited space. The space barrier environment is complex, and the LNG jet fire easily hits the wall of the equipment shell, thus forming a barrier wall. Gas jet fire. ...

AI Technical Summary

Problems solved by technology

In fact, unlike the traditional open space, the engine room of a ship is equipped with power equipment, electrical devices, control pipelines, etc. The walls of these obstacles are not simple vertical / horizontal walls, but equipment walls with a certain inclination angle and circular Curved walls of pipelines are very common. The law of momentum loss in the process of LNG gas jet fire hitting such unconventional walls has not yet been clarified. The behavior characteristics of the wall gas jet fire plume formed after the impact will be obviously different. Automatic Fire Suppression Systems Bring New Challenges

[0004] However, at present, there are relatively few studies on the combustion characteristics of gas jet fires in ship engine rooms under different jet angles and barrier wall conditions, and the corresponding experimental simulation research platform is even more lacking.
