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

Abstract

Purpose

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.

Design/methodology/approach

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

Findings

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.

Originality/value

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.
