This study aims to investigate heat and mass transfer in a one-row heat exchanger. The required
equations are obtained based on two-dimensional model analysis in a cell of the heat exchanger. By using
finite difference approach, the obtained equations are solved to determine distribution of temperature and the
efficiency of the heat exchanger in the case of partially wet surface. In this research, Lewis Number as unity
and water vapor saturation as parabolic are assumed. Obtained results show that increase in thermal
conductivity fin leads to decreasing thermal resistance; therefore, temperature changes in radial from center
to out of fin are reduced and efficiency of fin increases.
