Abstract:
This paper presents the analytical solution of steady
state governing equation for a rectangular fin subjected to
simultaneous heat and mass transfer (i.e. wet fin) across the
surface as well as at the tip of the fin. The temperature
distribution is obtained by using homotopy analysis method for
the insulated as well as for the convective fin tip boundary
conditions. Earlier studies on wet fin have been restricted to the
analysis of nonlinear governing equation with insulated tip
condition only. The present study developed a closed-form
solution with consideration of nonlinearity effects in both
governing equation as well as in the boundary condition.
