Thermal Diffusivity of H2O near the Critical Point



Jan V. Sengers, Richard A. Perkins, Marcia L. Huber, Bernard Le Neindre


The asymptotic critical behavior of the thermal diffusivity of H2O, deduced from dynamic light-scattering measurements, is shown to be in good agreement with the mode-coupling theory for critical dynamics in fluids. Consistency of the thermal-diffusivity measurements with the critical enhancement of the viscosity of H2O is also demonstrated.
