Superheating limits of liquid helium I
It is shown that the maximum superheat temperature ΔT max 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...

description | It is shown that the maximum superheat temperature
ΔT
max
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
ΔT
max
can be obtained from the kinetic limit of super-heat (homogeneous nucleation temperature). Experimental data on the homogeneous nucleation superheat temperature,
ΔT
h
, in liquid helium I over an extended temperature range are presented and compared with the
ΔT
max
measurements of several investigators. It is pointed out that in any quantitative predictions of
ΔT
max
, a knowledge of
ΔT
h
alone is not sufficient. In fact, the measured value of
ΔT
max
can lie either below or even above
ΔT
h
depending on the bath temperature, conditions of the surface, and the thermophysical properties of both heater and liquid. |
