Abstract
In the present case study, a highly idealized situation of an incompressible fluid flowing horizontally over a flat surface, consisting of a volatile liquid in a saturated state undergoing vaporization, is considered. The problem is similar to that reported by Bird et al. [1], but allowance is made for cases in which heat and mass transfer is sufficiently high to make it necessary to allow for significant temperature and concentration variations in the boundary layer. The situation that is taken into consideration here is similar to the one analysed by Bird et al. [1]. The present approach yields a lower bound estimate of the heat and mass transfer coefficient, and it is anticipated that the experimental values (though extremely difficult to find until now) will lie in-between the predictions given by Bird et al. [1] and the present results. The case study aims to develop suitable correction factors for the heat and mass transfer coefficients when the mass flux at the interface is high.
