Abstract
The present work numerically examines the entropy generation in the transport of hyperbolic tangent nanofluid over a stretchable surface with nonlinear Boussinesq approximation. Impacts of viscous dissipation, Joule heating, strength of uniform magnetic field along with modified Arrhenius expression is accounted. Under the significance of Buongiorno’s model, thermophoresis and Brownian effects are considered. The dimensionless form of mathematical system is obtained by adopting similarity variables. Consequence of flow parameters are explored through graphs. More, drag coefficient, heat transfer rate and Sherwood number are presented with tables and bar charts. Here, we noted that power law index parameter declines the fluid motion and entropy generation increases with diffusion variable.
