Author(s): 
Pages: 625-628
Year: Issue:  6
Journal: Journal of Chongqing University(Natural Science Edition)

Keyword:  石墨泡沫多孔材料达西定律容积导热系数;
Abstract: 通过对石墨泡沫材料内部微几何结构的分析,建立了流动和导热的数值分析模型.计算并分析了材料孔隙内压力梯度与流速的关系,证明了孔内压力梯度与流速的二次方关系,渗透率的计算结果与相关文献的理论分析和实验结果吻合较好.研究了在有流体通过孔隙并与孔壁有对流换热的情况下,流速和孔隙率对石墨泡沫材料容积导热系数的影响.
