چکیده
The development of the mathematical model of mass transfer and diffusion process can determine the behavior of dissolved impurities in the flow boiling within viscous sublayer. Application of a new model to calculate the distribution of dissolved impuritiesconcentration within viscous sublayer and estimation of its thickness based on heat conduction layer and evaporation layer (macro-microlayer model) is the major goal of this study.
