Duel Solutions in Hiemenz Flow of an Electro-Conductive Viscous Nanofluid Containing Elliptic Single-/Multi-Wall Carbon Nanotubes With Magnetic Induction Effects

Abstract Modern magnetic nanomaterials are increasingly embracing new technologies including smart coatings, intelligent lubricants, and functional working fluids in energy systems. Motivated by studying the manufacturing magnetofluid dynamics of electroconductive viscous nanofluids, this work, we analyzed magnetohydrodynamics (MHD) convection flow heat transfer an incompressible nanofluid containing carbon nanotubes (CNTs) past a stretching sheet. Magnetic induction effects included. Similarity solutions derived where possible addition to dual branch solutions. Both single-wall (SWCNTs) multi-wall (MWCNTs) considered taking water kerosene oil as base fluids. The governing continuity, momentum, induction, conservation partial differential equations converted coupled, nonlinear systems ordinary via similarity transformations. emerging control parameters shown be Prandtl number (Pr), nanoparticle volume fraction parameter (φ), inverse (λ), body force (β) rate (A), type nanotube. Numerical boundary value problem conducted with efficient bvp4c solver matlab. Validation earlier studies is Computations reduced skin friction wall (Nusselt number) also comprised order identify critical values for existence (upper lower branch) velocity, temperature, induced field functions. Dual exist some cases studied. simulations indicate that when ratio less than 1, SWCNT nanofluids exhibit higher velocity MWCNT increasing water- kerosene-oil-based CNT nanofluids. Generally, achieve enhanced performance compared Water-based attain greater acceleration
