助燃剂对木垛火燃烧特性影响研究

蚁群算法是近几年优化领域中新出现的一种启发式仿生类并行智能进化系统,该算法采用分布式并 行计算和正反馈机制,易于与其他方法结合,目前已经在众多组合优化领域中得到广泛应用。在介绍基本蚁群 算法数学模型的基础上,列举了进入２１世纪以来部分具有代表性的蚁群算法改进模型及其应用情况,然后重点 从算法的模型改进、理论分析、并行实现、应用领域、硬件实现、智能融合等角度对蚁群算法在今后的研究方 向作了系统分析与展望。

Accelerant Influence on Combustion Characteristics of Woo d Crib Fire

Combustion characteristics of wood crib fire under two different conditions, i.e. accelerant added and not added, was studied to investigate the accelerant effect on combustion characteristics of combustible materials. The experiments were carried out in a full-scale room in accordance with ISO 9705, where multi-parameters were measured, such as heat release rate, mass loss rate, temperature field and species concentration. At the same time, this process was numerically simulated. The computational results were consistent with experiment data.
