The impact of exothermic catalytic chemical reaction and viscous dissipation
on natural-convection heat transfer along the curved shape is investigated.
In this study, the trend of exothermic catalytic chemical reaction has been
introduced in the energy and mass concentration equation. Furthermore, the
tangential component of acceleration due to gravity, gx, as buoyancy force
has coupled in momentum equation describe the curved shape. The flow model
of the problem is formulated in terms of coupled non-linear PDE together
with suitable boundary conditions. From the numerical solutions of the
governing equations, it is found that velocity field, temperature
distribution and the mass concentration is associated with the dimensionless
parameters involved in the flow model. The novelty of the current study is
that the characteristics of heat and fluid-flow mechanism are specifically
associated with the different values of index parameter n.
