Heat transfer coefficients have been obtained for natural‐convection film boiling of helium I on single wires with a diameter ranging from 5 to 50 μ. The measurements covered temperature differences of 30° to 1,000 °K. between the heating surface and the saturated liquid under atmospheric pressure. The results are correlated in dimensionless from (Nusselt number vs. the product of the Grashof and Prandtl numbers) and compared with data for nitrogen and measurements of other investigators on film boiling of liquefied gases.
