Thermal Properties of Deuterium Oxide near the Triple Point Predicted from Nonequilibrium Evaporation

Abstract

Statistical rate theory (SRT) was applied to predict the saturation pressure of D 2 O numerically near the triple point based on the interfacial liquid-phase temperature, the interfacial vapor-phase temperature, and the local evaporation flux from 102 local measures in a series of nonequilibrium steady-state droplet evaporation experiments. An analytical expression of the saturation pressure, P sat , was obtained from the predicted values. Following the thermodynamic relations, the specific entropy of evaporation, h fg , and the liquid-phase specific heat at constant pressure, C p L , were computed. The agreement that the calculated values of these properties with those obtained from the independent measurements indicates that the SRT expression accurately predicts the thermal properties of D 2 O near the triple point.

“…Printing and refrigeration are two instances in daily life; besides, fabrication of new materials is a successful example of high technological evaporation. [1][2][3] Evaporation is a complex process so that many scientists discovered the secret of this natural phenomenon. In 1820, John Dalton began experiments and studies on evaporation mechanism.…”
