Roles of γAl2O3-H2O and γAl2O3-EG with thermal radiation on MHD flow across porous stretching-shrinking nonparallel channels
The current examination focuses on comparative heat transfer exploration in the MHD flow of γ− nanoparticles between nonparallel flow for both base fluids (i.e., ethylene glycol and water). Considering the radiation, stretchable walls, and the flow in porous media. The modeling process involves tran...

| description | The current examination focuses on comparative heat transfer exploration in the MHD flow of γ− nanoparticles between nonparallel flow for both base fluids (i.e., ethylene glycol and water). Considering the radiation, stretchable walls, and the flow in porous media. The modeling process involves transforming nonlinear partial differential equations (PDEs) like continuity, momentum, and heat equations into a system of nonlinear ordinary differential equations (ODEs) using similarity transformations. The Daftardar-Jafari method (DJM) is used to construct an analytical solution for the Jeffery-Hamel problem, which was then compared with results from the HAM-constructed Mathematica software and Runge-Kutta Fehlberg 4th–5th order (RKF45) for authorisation. The impact of involved factors like Prandtl number, solid volume fraction, base fluid, Darcy number, stretchable walls, and thermic radiative fluxing on velocity, temperature, surface frictional force, and Nusselt number. Improving viscous dissipation and radiative fluxing drops the rates of heat transport in both γAl2O3−H2O and γAl2O3−EG nanofluids. It is found that the increment of nanoparticles volume fraction improves Nusselt numbers by up to 18.5 % in EG instead of water as base fluid. The study is innovative because it uses both analytic and computational techniques along with a porous radiated channel that contains nanofluid. |
