Effects of chemical reaction and radiation absorption on mixed convective flow in a circular annulus at constant heat and mass flux

K. Ramesh Babu, B. Venkateswarlu and P. V. Satyanarayana

In this paper, the effects of chemical reaction, radiation absorption on mixed convective heat and mass transfer, flow of a viscous fluid through a porous medium in a cylindrical region between concentric circular cylinders r = a and r = b in the presence of heat generating sources are dealt appropriately. Hear, the outer cylinder r = b is maintained at a constant heat and mass flux. The relation between the temperature is explained in the equation of state and constant heat source in the field region. The governing non-linear partial differential equations can be transformed into a system of ordinary differential equations are them solved by using Gauss-Seidal Iteration method. The effect of variation of governing parameters on the flow heat and mass transfer characteristics are discussed through the graphs and tables
