Summary

IT IS SHOWN THAT THE MAXIMUM SUPERHEAT TEMPERATURE DTM IN LIQUID HELIUM I, DETERMINED UNDER STEADY-STATE PEAK NUCLEATE BOILING CONDITIONS, CANNOT BE REALISTICALLY ESTIMATED FROM THE THERMODYNAMIC LIMIT OF SUPERHEAT (SPINODAL), AS HAS BEEN PREVIOUSLY CLAIMED. IT IS SUGGESTED THAT A MORE MEANINGFUL ESTIMATE OF DTM CAN BE OBTAINED FROM THE KINETIC LIMIT OF SUPERHEAT (HOMOGENEOUS NUCLEATION TEMPERATURE). EXPERIMENTAL DATA ON THE HOMOGENEOUS NUCLEATION SUPERHEAT TEMPERATURE, DTH, IN LIQUID HELIUM I OVER AN EXTENDED TEMPERATURE RANGE ARE PRESENTED AND COMPARED WITH DTH MEASUREMENTS OF SEVERAL INVESTIGATORS. IT IS POINTED OUT THAT IN ANY QUANTITATIVE PREDICTIONS OF DTM, A KNOWLEDGE OF DTH ALONE IS NOT SUFFICIENT.
