Chamber fire simulation experiment device under action of external wind

Abstract

The invention provides a chamber fire simulation experiment device under the action of external wind. The device can simulate chamber fire combustion conditions in a laboratory under the action of the external wind and can be used for researching chamber fire development and windowsill overflow rules under the action of the external wind. The chamber fire simulation experiment device under the action of the external wind comprises an experiment table body, an outer vertical face, an external wind system and a matched measurement and control system. The device is designed according to a medium-size model proportion of 1:3 and is the first experimental device carrying out comprehensive and systematic study on the heat release rate, smoke flowing, temperature distribution, smoke compositions, the air supplement speed, thermal radiation flux, flame forms, sill overflowing and the like of a chamber fire under the action of the external wind. On the basis of previous experimental bases, the defects that a full-scale experiment is high in cost and a numerical simulation tool is not precise enough are overcome, repeatability of the experiment is guaranteed, and the device has great application value and important guiding significance in conducting laboratory scientific research and influences of actual external wind on the chamber fire.

Description

technical field [0001] The invention belongs to the technical field of fire safety, and specifically relates to a chamber fire simulation experiment device under the action of external wind, which is specifically for studying the heat release rate, smoke flow, temperature distribution, smoke composition, supplementary Simulated experimental setup for wind speed, thermal radiation flux, flame shape, and window sill overflow. Background technique [0002] With the development of my country's economy, the number of high-rise buildings is increasing, the height is getting higher and higher, and the structure is becoming more and more complex. With the occurrence of a large number of high-rise building fires, the fire safety of high-rise buildings has aroused people's extensive attention and deep thinking. When a fire breaks out in a high-rise building, the flames in the burning room spread upward through broken windows, endangering the safety of people on other floors. The bot...

Problems solved by technology

[0007] Because the full-scale fire experiment needs to mobilize a lot of manpower and material resources, the economic cost is large, it is greatly affected by various factors, the conditions are difficult to control, and the repeatability is poor, so it is not easy to carry out
