Abstract
The vapor removal mechanism during film boiling on horizontal cylinders has been observed over an 81-fold variation of gravity and a tenfold variation of radius. These measurements are the basis for an assessment of prior predictions of wavelength. A significant low-gravity transition point in the vapor removal mechanism is identified and explained. “Best” formulas are recommended for the prediction of the wavelength and the minimum heat flux. These depend upon a single parameter which represents both size and gravity.Keywords
