The Chemical Engineering Science Division (Boulder, Colorado) of the National Institute of Standards and Technology has investigated transient heat transfer to liquid hydrogen. Thin carbon films and Pt foils submerged in liquid hydrogen received stepped power inputs of 1 to 42 W/cm2, and the onset of nucleate or film boiling was obtained for each power level. The critical heat flux was found to be approximately 8 W/cm2, with the transition to film boiling occurring in times less than 10-3s. Premature film boiling can be related to the positive temperature coefficient of resistance and the narrowness of the Pt heaters.
