Abstract

AbstractThis paper examines the heat transfer characteristics of free convection boundary layer flow over a stretching Sheet with a hybrid nanofluid in the Casson field subject to constant heat flux boundary condition. The dimensional governing equations and boundary layer equations are transformed into partial differential equations (PDEs) using some suitable similarity transformation and physical properties. The Keller box method which is an implicit finite difference technique was applied to obtain the numerical solution of the corresponding PDEs. Numerical computations are done using the MATLAB subroutine programming and the results are presented in tables and figures. The impacts of hybrid nanofluids Casson parameters on the local skin friction coefficient and local Nusselt number, beside the velocity and temperature is studied. Hybrid nanofluid has a lower velocity and temperature in addition to possessing the highest local Nusselt number when compared with nanofluid. The outcomes of the local Nusselt number and the wall temperature for the Newtonian fluid are detected to be in perfect accuracy with the literature.KeywordsMagnetohydrodynamicHybrid nanofluidCasson fluidStretching sheet
