Analysis of thermodynamic process of water vapor in boiler [PDF]
E3S Web of Conferences, 2021 In steam power plant, the working medium used for energy transformation is water vapor. The generation process of water vapor has experienced three stages: pre-heat, vaporization and superheat stage. There are five states in the process.

Macroscopic water vapor diffusion is not enhanced in snow [PDF]
The Cryosphere, 2021 Water vapor transport in dry snowpacks plays a significant role for snow metamorphism and the mass and energy balance of snowpacks. The molecular diffusion of water vapor in the interstitial pores is usually considered to be the main or only transport ...
