Boiling incipience of highly wetting liquids in horizontal confined space

This study concerns boiling incipience of highly wetting liquids ( n-pentane), in transient conditions, in horizontal confined space between a vertical heating cylinder and a disk. The two controlled parameters were the heat flux, ranging from 50 to 200 kW m −2 and the thickness of the liquid in the...

Zusammenfassung:	This study concerns boiling incipience of highly wetting liquids ( n-pentane), in transient conditions, in horizontal confined space between a vertical heating cylinder and a disk. The two controlled parameters were the heat flux, ranging from 50 to 200 kW m −2 and the thickness of the liquid in the confined space, ranging from 0 to 240 μm. Experiments were conducted with both smooth and porous disks. The results suggest that in the porous-disk configuration, boiling could appear on the non-heated wall.
