COMPUTATIONAL ANALYSIS OF NATURAL CONVECTION FLOW DRIVEN ALONG A CURVED SURFACE IN THE PRESENCE OF EXOTHERMIC CATALYTIC CHEMICAL REACTION

The phenomena of exothermic catalytic chemical reaction for two-dimensional, steady-state natural convection flows along a curved surface under the effect of different controlling parameters are examined numerically. The primitive variable formulation for the finite-difference method is used to solve the coupled momentum, energy, and mass transport equations. Based on the results of this study, it is found that the activation energy parameter epsilon, the heat reaction parameter alpha, the Schmidt number Sc, and the body shape parameter n played significant roles on natural convection flow in the presence of an exothermic catalytic chemical reaction. Moreover, the accuracy of the numerical scheme is validated by a comparison of the obtained results for various values of the body shape parameter n with those reported in the literature, and they are found to be in excellent agreement.
