Helium was condensed on the wall of a vertical copper tube (14mm i. d., 32mm long) in the experimental range, Vapor temperatures in a tube 4.1-5.0K Heat fluxes 0.5-86mW/cm2 Temperature differences across a liquid film 0.01-1.3K Film Reynolds numbers 3-380 The heat flux was found to increase linearly with the film temperature difference, yielding a constant heat transfer coefficient of about 0.065W/cm2K. The discrepancy between the experimental results and the laminar condensation theory is also discussed.
