摘要
基于流体力学和射流理论,采用CFD软件,数值模拟了有无通风2种状况下掘进工作面煤燃烧的火灾发展变化过程。模拟结果表明局部通风形成复杂流场,且明显加速了火灾的蔓延和烟气的流动,验证了局部通风机"保持原状"的控制原则,为实际救灾提供了一定的理论依据。
In this paper, based on hydrodynamic and jet theory, a CFD software was adopted to simulate the development process of fire in heading face. It was showed that complicated flow field was formed because of local ventilation. It also can be seen that ventilation accelerated fire spread and smoke flow. The results verified the principal of controlling secondary fan （ that is＂ Leave it as it is＂ ） and provided theoretical basis for practical operation of extinguishing fire.
