摘要：
This work used an integral method to study the combined heat and mass transfer by free convection from horizontal cylinders embedded in the fluid saturated porous media with constant wall temperature and concentration. The results obtained by the integral method agree well with the solutions calculated by similarity analysis. It is very easy for engineers to use the closed-form integral solution presented in this study for obtaining average and local values of heat and mass transfer characteristics. The asymptotic results for the heat and mass transfer rates were studied and the distinct asymptotic regimes were found for the heat transfer rate and the mass transfer rate. The corresponding heat and mass transfer rate expressions were also derived and presented.
