Description

technical field [0001] The invention belongs to the technical field of fire safety, and relates to a wide water surface oil pool fire combustion simulation device, in particular to a wide water surface oil pool fire combustion simulation device under the action of ambient wind. Background technique [0002] In recent years, in the process of offshore oil exploitation and transportation, oil spill accidents have occurred frequently, and the leaked fuel oil will form a large-scale oil pool fire on the ocean surface, causing major economic losses and damage to the marine environment. Therefore, the research on oil pool fires on wide water surfaces, especially the research on oil pool fires on wide water surfaces under the action of ambient wind has gradually become the focus. At present, the research on oil pool fires on the water surface mainly includes small-scale and large-scale experimental research and numerical simulation research. Due to the large scale, high test cost ...

AI Technical Summary

Problems solved by technology

The oil pool fire formed by the actual marine fuel oil leakage is a wide water surface oil pool fire, that is, the water surface area can be approximately infinite compared with the oil pool fire area, and the existing combustion device simulates the water surface oil pool by adding a water pad under the oil layer Fire, so that the area of ​​the water layer is consistent with the fire area of ​​the oil pool, which is inconsistent with the actual situation of the oil pool fire formed by the leakage;

[0005] (2) Experimental error caused by wall heat transfer

During the experimental process of the oil pan of the existing combustion device, the height of the fuel liquid level will gradually decrease with the combustion reaction, resulting in the effect of wall surface heat transfer in the heat transfer process of the combustion experiment. The heat transfer process of wall combustion is obviously different, which makes the experimental results deviate from the actual wide water surface oil pool fire combustion
