Abstract
The natural convection boundary layer flow of a viscous incompressible fluid with temperature dependent viscosity and thermal conductivity in the presence of exothermic catalytic chemical reaction along a curved surface has been investigated. The governing non dimensional form of equations is solved numerically by using finite difference scheme. The numerical results of velocity profile, temperature distribution and mass concentration as well as for skin friction, heat transfer rate and mass transfer rate are presented graphically and in tabular form for various values of dimensionless parameters those are generated in flow model during dimensionalization. From the obtained results, it is concluded that the exothermic catalytic chemical reactions is associated with temperature dependent viscosity and thermal conductivity. Further, it is concluded that the body shape parameter also plays an important quantitative role for change in velocity profile, temperature field and mass concentration behavior in the presence of exothermic catalytic chemical reaction.
Highlights
The idea of natural convection heat transfer along the curved surface in the presence of exothermic catalytic chemical reaction represents an idealization of many significant issues in engineering practice
It can be observed that the velocity has increased prominently near the surface as viscosity variation parameter has increased, whereas the temperature and mass concentration have decreased with the increasing γμ
The results indicate that the velocity boosts up with an increase in viscosity variation parameter γμ, whereas a decreasing behavior is observed in the temperature and mass concentration
