摘要

The present article provides mathematical modeling for melting heat and thermal radiation in stagnationpoint flow of carbon nanotubes towards a nonlinear stretchable surface of variable thickness.The process of homogeneousheterogeneous reactions is considered.Diffusion coefficients are considered equal for both reactant and autocatalyst.Water and gasoline oil are taken as base fluids.The conversion of partial differential system to ordinary differential system is done by suitable transformations.Optimal homotopy technique is employed for the solutions development of velocity,temperature,concentration,skin friction and local Nusselt number.Graphical results for various values of pertinent parameters are displayed and discussed.Our results indicate that the skin friction coefficient and local Nusselt number are enhanced for larger values of nanoparticles volume fraction.
