摘要：

Present analysis examines boundary layer flow of carbon nanotubes over a curved stretching surface. Instead of classical Fourier law we employed Cattaneo-Christov heat flux theory. The heterogeneous reaction taking place on the wall surface are given by isothermal cubic autocatalytic kinetics. The homogeneous reaction occurring in the ambient fluid are governed by first order kinetics. Appropriate transformations are employed to obtain system of nonlinear ordinary differential equations. Convergent series solution are obtained. Single and multi wall carbon nanotubes are used. Water is taken as a base fluid. Fluid flow, temperature, concentration, skin friction coefficient and Nusselt number are examined and analyzed for different involved parameters. (C) 2017 The Authors. Published by Elsevier B.V.
