Joule heating effect on the MHD flow of tangent hyperbolic mixed nanofluid embedded with MgO and CuO nanoparticles

Abstract

The present article emphasises on the study of the two-dimensional, steady, electrically conducting tangent hyperbolic mixed nanofluid flow across a linear/nonlinear elongating sheet with Joule heating and uneven heat source effect. The mixed nanoliquid is the amalgamation of oxides of Magnesium and Copper nanomaterial suspension in the methanol liquid. The governing yielded equations are resolved by adopting the bvp5c Matlab tool. The novelty of this research is to determine the enhanced energy transmission between linear and nonlinear extending sheet instances. The flow and temperature profiles for various constraints are graphed; furthermore, the wall friction and energy transmission rates are demonstrated via numeric values. The energy transmission rate in the nonlinear extending case is more substantial than the linear case in the nanoparticle volume factor. Also, uneven heat source and Joule heating parameters effectively amplify the thermal curves for both criteria.
