| 摘 要： | 提出了基于分块耦合的双分布格子Boltzmann方法(LBM)的地下巷道热流态仿真模型。在该模型中,分别建立了LBM速度和温度模型,并采用Boussinesq方程将其有机耦合;平直边界采用反弹格式处理,曲边界采用曲边界反弹格式处理;采用分块耦合算法将复杂巷道分成若干规则块,各块分别独立计算,在边界处交换数据,从而去除冗余网格,简化网格计算,提高系统资源利用效率。通过基于该模型开发出的仿真系统的运行表明,该仿真系统将时间、空间和系统各参数有机结合起来,在形象、直观的条件下观测到火灾发生时地下矿巷道系统热流的演变过程,获得巷道系统关于热流流动速度,温度,压力等方面的详细数据,为制定行之有效的热流规避方案提供科学依据。

| Abstract: | The heat flow model of an underground tunnel system based on dual-distributed Lattice Boltzmann Method(LBM) of separated-coupled algorithm was proposed.In the model,the LBM velocity and temperature models were constructed respectively,and then these models were coupled organically by Boussinesq equation;the bounce-back scheme on a straight boundary and the curved-boundary-bounce-back scheme on a curved boundary were adopted respectively;a complicated tunnel in the underground tunnel system was divided into ... |
