Comparative study of MHD boundary layer flow of hybrid nanofluid in a channel

Abstract

AbstractThe interest of this study is to comprehensively explore the boundary layer flow of hybrid nanofluid within two infinite horizontal plates under the impact of magnetohydrodynamics (MHD), viscous and magnetic dissipation. The fluid is colloidal mixture of water and a very dilute suspension of Copper Oxide and Silver The flow is generated as a result of uniformly stretching of lower plate in direction. Nonlinear governing equations are modified into ordinary differential equations by nondimensional transformation. MATLAB based bvp4c and Mathematica based NDSolve are employed to compute the solutions of the reduced equations. A numerical and graphical comparison is done between bvp4c and NDSolve to verify the findings. The influence of significant parameters like magnetic field, Reynolds number, Prandtl number, Eckert number and heat absorption/generation are computed graphically. Additionally, numerical information about the heat mass flux is also tabulated to achieve complete picture of heat related data and evaluate its impact on flow dynamics. The outcomes of the present analysis can be used in various engineering processes where nanoparticles enhance thermal conductivity and conservation of energy.
