应用电子计算机进行矿井通风设计和自动控制,首先必须研究通风网路中风流的流动规律,建立数学模型。目前,国外在这方面的研究大多数将矿井空气当作不可压缩的流体,不考虑风流与其周围介质之间的能量交换过程。实践证明,这种处理方法不能全面地反映矿井通风的状态,尤其是在矿井内发生灾变的情况下更属如此。本文将矿井空气当作可压缩的流体,并考虑风流与其周围介质之间的能量交换过程,根据流体力学和热力学的基本规律来研究矿井内风流的流动规律,建立控制矿井通风网路中风流状态的数学模型。
Application of electronic computer for mine ventilation design and automatic control, we must first study the flow of ventilation network flow law, the establishment of mathematical models. At present, most researches in this field abroad regard mine air as an incompressible fluid, irrespective of the energy exchange process between the wind flow and the surrounding medium. Practice has proved that this approach does not fully reflect the status of mine ventilation, especially in the event of a disaster in the mine even more so. In this paper, the mine air is regarded as compressible fluid, and the energy exchange process between the wind flow and the surrounding medium is considered. According to the basic law of fluid mechanics and thermodynamics, the law of flow in the mine is studied. Mathematical model.
