Case study of radiation absorptive and chemical reactive impacts on unsteady MHD natural convection flowing of Cu-Al2O3/H2O hybridized nanofluid

Abstract

Magnetohydrodynamic hybrid nanofluid (Cu-Al2O3/H2O) flow along an infinitely long plate accelerated exponentially with constant species diffusion, varying heat source and under the chemical reactive, radiation absorptive influences are analysed. Non-dimensional partial differential equation system is derived from the governing nonlinear boundary layer equations. Both analytical and numerical solutions to these equations are obtained using Laplace transform approach and finite difference method. The investigation has been conducted across a broad spectrum of magnetic parameters, thermal Grashof numbers, mass Grashof numbers, radiation absorption parameters, and chemical reaction parameters. Graphical representations are used to show the implications of factors like Schmidt number, mass Grashof number, chemical reactive variable, thermal Grashof number, absorption of radiation on flow, heat, mass transfer and on their gradients as well. Velocity enhances with rising amounts of thermal and solutal buoyancy forces. Reversal tendency is noticed in situation of chemical reaction parameter and magnetic field parameter. Temperature transmission rate of hybrid nanofluids is higher than conventional nanofluids and pure fluids.
