The analysis of Rivers and McFadden for film boiling heat transfer from horizontal cylinders immersed in Helium II is briefly reviewed and results are recapitulated. Experimental measurements of film boiling heat transfer are made for horizontal cylinders of 0.145 cm and 0.245 cm dia immersed in Helium II baths at 1.78, 1.96, and 2.1 K at wall heat fluxes up to 2.84 w/cm2. The nondimensionalized experimental results are compared with the accepted correlations of Bromley and Breen and West-water to demonstrate the inability of the usual film boiling correlations to predict film boiling in Helium II. The nondimensionalized experimental results are compared with the predictions of the Rivers and McFadden analysis which considers Helium II properties, and the results of the analysis are substantiated.
