摘要
研究了PMF法形成的泡沫金属,在自然对流和强迫对流两种状态下其孔隙结构(孔径、孔隙率、通孔度)及试样厚度对其换热性能的影响,并对实验结果作了讨论。
The influence of pore-structure on heat exchange ability of metallic foam is investigated in the conditions of force-convection and natureconvection. The results show that In the conditions of force-convection and nature-convection, the convective heat exchange ability of metallic foam is rather different. Force-convection increases the heat exchange ability greatly compared with the nature converction. Pore structure affects its heat exchange ability. However, the influence is little, especially in the force-convection condition
