对浸泡在饱和FC-72介质流体中的纳米多孔表面的池沸腾换热进行了实验研究。用Whatman公司的氧化铝(Al_2O_3)制成的厚度约为70μm的纳米多孔表面(阳极盘25)与厚度约为105μm的平面(铝)的实验数据进行了比较，从实验数据可以明显地看出，纳米多孔表面相对于平面表面的初始过热能降低了约30%。用扫描电子显微镜对纳米多孔涂层进行了分析，确定了涂层的孔径大小。
Pool boiling heat transfer from nano-porous surface immersed in a saturated FC-72 dielectric fluid has been experimentally studied at atmospheric pressure (101 kPa). The data obtained from nano-porous surface (Anodisc 25) of thickness about 70 μm made from aluminum oxide (Al2O3) obtained from Whatman, were compared to that of a plain surface (aluminum) of thickness about 105 μm. From the experimental data obtained it was evident that there is a reduction of about 30% in the incipient superheat for the applied power for nano-porous surface over plain surface. SEM photographs of the nano-porous coating were taken for determining the size of the pores.
