Diffusion Layer Theory for Turbulent Vapor Condensation With Noncondensable Gases

TLDR: In this paper, the authors derived an effective condensation thermal conductivity by expressing the driving potential for mass transfer as a difference in saturation temperatures and using appropriate thermodynamic relationships, and demonstrated that condensation obeys the heat and mass transfer analogy, when condensation and sensible heat tranfer are considered simultaneously.

Abstract: In turbulent condensation with noncondensable gas, a thin noncondensable layer accumulated and generates a diffusional resistance to condensation and sensible heat transfer. By expressing the driving potential for mass transfer as a difference in saturation temperatures and using appropriate thermodynamic relationships, here an effective condensation thermal conductivity is derived. With this formulation, experimental results for vertical tubes and plates demonstrate that condensation obeys the heat and mass transfer analogy, when condensation and sensible heat tranfer are considered simultaneously
