Coupled heat and mass transfer by free convection over a truncated cone in porous media: VWT/VWC or VHF/VMF. (English) Zbl 0946.76090

From the summary: We analyze numerically heat and mass transfer characteristics of natural convection about a truncated cone embedded in a saturated porous medium and subjected to the coupled effects of thermal and mass diffusion. The surface is maintained at variable wall temperatue/concentration (VWT/VWC) or variable heat/mass flux (VHF/VMF). The transformed governing equations are solved by Keller box method. Numerical data for dimensionless temperature profiles, dimensionless concentration profiles, local Nusselt number and local Sherwood number are presented for wide range of dimensionless parameters.
