Anyone knows the Surface Roughness factor(Rp) value for Coooper correlation to find heat transfer for pool Boiling of Plain Copper surface?

09 April 2019 1 910 Report

I need to calculate Pool Boiling heat Transfer coefficient value by using Cooper correlation. My test specimen is Plain Copper surface.I used emery paper (CC261: 1000) to polish surface before testing.

We did some experiments about the impact of Sq on the Ceff of Cooper's correlation, but it is still very rough. The works are still on going. If you are interested, please read the paper:
