Theoretical analysis of the MHD flow of a tangent hyperbolic hybrid nanofluid over a stretching sheet with convective conditions: A nonlinear thermal radiation case

Abstract

The objective of this research is to examine the two-dimensional flow of a non-Newtonian water-based hybrid nanofluid containing silver and alumina nanoparticles over a stretching surface with convective conditions. The flow is considered to be steady, laminar and incompressible. The mathematical modeling of the flow analysis is considered in the form of partial differential equations which are then transformed into ordinary differential equations by mean of suitable similarity transformations. The present problem is solved with the help of semi-analytical technique called HAM. Convergence of HAM is shown with the help of Figure. The impacts of embedded parameters like magnetic parameter, Joule heating, activation energy and nonlinear thermal radiation on the flow profiles are displayed with the help of Figures and Tables. Our results showed that the greater magnetic parameter reduced the velocity profile, while a reverse impact magnetic parameter is found against temperature profile, skin frication and heat transfer rate of the hybrid nanofluid. Concentration profiles of the hybrid nanofluid flow are augmented with the increasing activation energy while reduced against chemical reaction parameter. Sherwood number has shown increasing behavior due to larger value of Schmidt number and decreasing on larger value of temperature relative parameter.
