Adiabatic nucleation in the liquid–vapor phase transition

Abstract

The fundamental difference between classical (isothermal) nucleation theory (CNT) and adiabatic nucleation theory (ANT) is discussed. CNT uses the concept of isothermal heterophase fluctuations, while ANT depends on common fluctuations of the thermodynamic variables. Applications to the nonequilibrium liquid to vapor transition are shown. However, we cannot yet calculate nucleation frequencies. At present, we can only indicate at what temperatures and pressures copious homogeneous nucleation is expected in the liquid to vapor phase transition. It is also explained why a similar general indication cannot be made for the inverse vapor to liquid transition. Simultaneously, the validity of Peng–Robinson’s equation of state [D.-Y. Peng and D. B. Robinson, Ind. Eng. Chem. Fundam. 15, 59 (1976)] is confirmed for highly supersaturated liquids.

Molecular-dynamics simulation of argon nucleation from supersaturated vapor in the NVE ensemble

“…An alternative method to molecular-dynamics simulation is Monte Carlo simulation which has also been applied for the investigation of homogeneous nucleation. 28 However, a NVE ensemble should not be able to exhibit nucleation as mentioned above. If this heat is not removed from the system the clusters formed by nucleation would heat up and likely evaporate again.…”

Blast from explosive evaporation of carbon dioxide: experiment, modeling and physics

“…Different choices for the EOS can lead to different values [1,2]. De Sá et al [11], Delale et al [12] and Abbasi and Abbasi [2] have investigated whether or not the TSL derived from an EOS is in agreement with experiments. In particular, the study of Abbasi and Abbasi gives a comprehensive set of results.…”
