Boiling heat transfer from a horizontal copper cylinder rotating on its axis in water has been investigated. An increase in heat transfer coefficient wag obtained over the entire range of rotational speeds with a maximum occurring at 150 rpm. The results were correlated in terms of the factors influencing the boiling mechanism, which differed above and below the critical speed. Below 150 rpm the effects of rotation were correlated by the inclusion of a Weber‐Reynolds number term in the boiling equation of Lienhard (1) , and above 150 rpm the same basic boiling equation was modified to include a Froude Number.
