Influence of Chemical reaction, Soret, Dufour and variable thermal conductivity effects on unsteady free convective flow between two concentric circular cylinders

Abstract

In this paper, the unsteady free convective flow of viscous incompressible fluid mixture between two concentric stationary circular cylinders under the influence of Soret, Dufour, Chemical reaction and variable thermal conductivity effects have been investigated. The flow equations corresponding to momentum, energy equations and species conservation equations are converted into dimensionless form, which are then, solved numerically based on finite difference method. The effects of material parameters on transient temperature and concentration profiles are discussed graphically.
