文中给出了不同陶瓷海绵的径向两相导热系数和壁面换热系数(材料、孔隙率和孔径的变化)的实验结果，揭示了表观风速和陶瓷海绵孔隙率对径向两相导热系数和壁面换热系数的强烈影响。对实验数据进行了无量纲关联，为今后估算海绵的径向两相导热系数和壁面换热系数提供了一个“普适”关联式。
In this publication, experimental results for the radial two-phase thermal conductivity and the wall heat transfer coefficient of different ceramic sponges (variation of material, porosity and pore size) are presented, revealing a strong influence of the superficial air velocity and of the porosity of the ceramic sponges on both the radial two-phase thermal conductivity and the wall heat transfer coefficient. The experimental data are correlated in dimensionless form to offer a “universal” correlation for estimating the radial two-phase thermal conductivity and the wall heat transfer coefficient of sponges in the future.
