Abstract
•Velocity profile is an increasing function of velocity ratio parameter.•Behavior of volume fraction of Iron oxide as nanoparticles for momentum and thermal boundary layer is opposite.•For heterogeneous reaction parameter concentration profile increases while decline for homogeneous reaction parameter.•Increasing behavior of Hartmann number on shear stresses is noticed.•Local Nusselt number is enhances for radiation parameter.
Present communication deals with the effects of homogeneous-heterogeneous reactions in flow of nanofluid by non-linear stretching sheet. Water based nanofluid containing magnetite nanoparticles is considered. Non-linear radiation and non-uniform heat sink/source effects are examined. Non-linear differential systems are computed by Optimal homotopy analysis method (OHAM). Convergent solutions of nonlinear systems are established. The optimal data of auxiliary variables is obtained. Impact of several non-dimensional parameters for velocity components, temperature and concentration fields are examined. Graphs are plotted for analysis of surface drag force and heat transfer rate.
