The dry-out heat flux (DHF) for the copper sphere beds was measured using the hydrogen generated at a high potential in the copper electroplating system of mass transfer. The uniform self-heating condition was simulated by the experimental methodology. The experimental apparatus consisted of a power supply, a data acquisition system, a polycarbonate cylinder containing the copper cathode beds and copper anode submerged in an aqueous solution of H2SO4. This study reported the experimental results for the bottom flooding condition with the 6 mm copper beds. The DHF data was obtained for the bed height of 20, 40 and 60 mm. The tendency of DHF on the bed height is similar to that of existing heat transfer studies. However, the absolute DHF value was quite different. We inspected the potential of the non-heating experimental method and reviewed further studies for reducing the discrepancy.
