[2I07] A study of copper oxidation for critical heat flux in downward-faced flow boiling

Keywords:Critical heat flux, Flow boiling, Bubble behavior, Oxidation effect

Copper was oxidized in the furnace and a flow boiling experiment was done. It was found that fewer bubbles were generated and lead to a higher CHF. The CHF enhancement could be beneficial to the real-world IVR-EVRC method.
