Water vapor distribution in protoplanetary disks [PDF]
ApJ 792, 2 (2014), 2014 Water vapor has been detected in protoplanetary disks. In this work we model the distribution of water vapor in protoplanetary disks with a thermo-chemical code. For a set of parameterized disk models, we calculate the distribution of dust temperature and radiation field of the disk with a Monte Carlo method, and then solve the gas temperature ...

A volume of fluid framework for interface-resolved simulations of vaporizing liquid-gas flows [PDF]
Journal of Computational Physics, 2019, Volume 399, 2019 This work demonstrates a computational framework for simulating vaporizing, liquid-gas flows. It is developed for the general vaporization problem which solves the vaporization rate based as from the local thermodynamic equilibrium of the liquid-gas system.

Meshfree One-Fluid Modelling of Liquid-Vapor Phase Transitions [PDF]
arXiv, 2022 We introduce a meshfree collocation framework to model the phase change from liquid to vapor at or above the boiling point. While typical vaporization or boiling simulations focus on the vaporization from the bulk of the fluid, here we include the possibility of vaporization from the free surface, when a moving fluid comes into contact with a ...

Interfacial instability induced by lateral vapor pressure fluctuation in bounded thin liquid-vapor layers [PDF]
arXiv, 2008 We study an instability of thin liquid-vapor layers bounded by rigid parallel walls from both below and above. In this system, the interfacial instability is induced by lateral vapor pressure fluctuation, which is in turn attributed to the effect of phase change: evaporation occurs at a hotter portion of the interface and condensation at a colder one ...
