Exponential space-dependent heat generation on Powell–Eyring hybrid nanoliquid under nonlinear thermal radiation.

Hybrid nanofluids were popularized by heat transfer fluids into higher surface strength, dispersion and diffusion prospects related into traditional nanofluid. The novel characteristics of a single-phase hybrid nanofluid profile coincidence in studying nanoparticles mass including base fluid mass to produce solid equivalent density and addition to solid equivalent specific heat about constant pressure. On this work, flow and volumetric entropy generation and convective heat transport on Powell–Eyring hybrid nanofluid have been consider. Hybrid nanofluids attend the space through the systematic horizontal porous stretching surface. Impact on exponential space-dependent heat generation and nonlinear thermal radiation was more combined on the specified sketch. Mathematical equations about conservation of energy, mass, entropy and momentum are interpreted below acceptance on boundary layer flow of Powell–Eyring hybrid nanofluid. Comparison results were collected as conversion away from governing partial differential equations into ordinary differential equations, applying correlation variables. Finite element method was an external for finding the relative results of decreased ordinary differential equations. Numerical computing was achieved about zinc oxide–gold water (ZnO–Au/H₂O) hybrid nanofluid and conventional gold water (Au–H₂O) nanofluid. The notable allegation indicated to the hybrid Powell–Eyring nanofluid was best thermal conductor although related into a conventional nanofluid and pure water. Every rising on Reynolds number and Brinkman number developed into total entropy for that structure. [ABSTRACT FROM AUTHOR]
