摘要
根据局部通风流场特点,应用计算流体力学CFD软件对掘进工作面的CH4与风流质量混合过程进行了模拟。选择采用Realizableκ-ε双方程模型,探讨了掘进工作面风流流场和CH4浓度分布规律,对比了油型气中的CH4在掘进巷道底板不同位置涌出的扩散规律。
According to the characteristics of local ventilation flow field, an simulation on the mixing process of airflow and CH4 in heading face with CFD fluent. The heading face airflow field and CH4 concentration distribution was discussed and the emission law of oil-type gas at different floor position was compared with the Realizable κ-ε double equation model.
