Heat and mass transfer by natural convection flow about a truncated cone in porous media with Soret and Dufour effects

– The purpose of this paper is to study the effects of chemical reaction, thermal radiation and Soret and Dufour effects of heat and mass transfer by natural convection flow about a truncated cone in porous media.

– The problem is formulated and solved numerically by an accurate implicit finite-difference method.

– It is found that the Soret and Dufour effects as well as the thermal radiation and chemical reaction cause significant effects on the heat and mass transfer charateristics.

– The problem is relatively original as it considers Soret and Dufour as well as chemical reaction and porous media effects on this type of problem.
