Abstract

This paper scrutinizes the consequences of radiation and heat consumption of MHD convective flow of nanofluid on a heated stretchy plate with injection/suction and convective heating/cooling conditions. The nanofluid encompasses with C u and A g nanoparticles. We enforce the suited transformation to remodel the governing mathematical models to ODE models. The HAM (homotopy analysis method) idea is applied to derive the series solutions. The divergence of fluid velocity, temperature, skin friction coefficient, local Nusselt number, entropy generation, and Bejan number on disparate governing parameters is exhibited via graphs and tables. It is seen that the fluid velocity in both directions is subsided when elevating the magnetic field and Forchheimer number. Also, the C u nanoparticles possess hefty speed compared to A g nanoparticles because the density of A g nanoparticles is high compared to that of C u nanoparticles. The fluid temperature upturns when enlarging the heat generation and radiation parameters. The skin friction coefficients and local Nusselt number are high in A g nanoparticles than in C u nanoparticles.

Highlights

E divergence of fluid velocity, temperature, skin friction coefficient, local Nusselt number, entropy generation, and Bejan number on disparate governing parameters is exhibited via graphs and tables
One of the facile methods is for increasing the thermal conductivity, nanosized metals such as copper, graphite, alumina, titanium, carbides, metal oxides, and nitrides are added to common base fluids. ese fluids enhance the heat transfer attributes. e 3D flow of waterbased nanofluid past a stretching sheet with three different types of nanoparticles was deliberated by Nadeem et al [1]
Hosseinzadeh et al [2] inspected the 3D flow of ethylene glycol-titanium dioxide nanofluid on a porous stretching surface with the convective heating condition. e skin friction coefficient exalts when aggravating the nanoparticle volume fraction parameter. e axisymmetric flow of silver and copper water-based nanofluids between two rotating disks was studied by Rout et al [3]. ey detected that the skin friction coefficient elevates when raising the solid volume fraction
