Flow boiling heat transfer of nitrogen at high subcritical pressure conditions in a single vertical mini-channel with the diameter of 2.0 mm was experimentally investigated. The tested mass flux varied from 530 to 830 kg/(m 2 ·s), the inlet pressure ranged from 630 to 1080 kPa, and the heat flux ran...
