摘要
主要从开孔金属泡沫微观组织的基本结构出发对开孔金属泡沫内的固体热传导、气体热传导和热辐射进行了分析,根据以上的分析利用能量方程和两热流法建立了开孔金属泡沫的传热模型,并利用试验对泡沫镍的有效导热系数进行了测量,泡沫镍的有效导热系数实验值验证了开孔金属泡沫传热模型的正确性。
Based on the fundamental micro-structure of open cell metallic, three heat transfer models of open cell metallic foams： solid conduction, gas conduction and thermal radiation, is analyzed. According to the analysis, heat transfer model of open metallic foams is founded by means of energy equation and two flux method. The experiment for measuring effective thermal conductivity of nickel foams is done and the heat transfer model of open metallic foams is identified by means of measuring values of effective thermal conductivity for nickel foams.
