MHD Flow of Hybrid Nanofluid Between Convergent/Divergent Channel by Using Daftardar-Jafari Method.

Alloys A A 7072 and A A 7075 are significant with thermal, physical, and mechanical characteristics; these are extensively used in manufacturing of spacecraft, aircraft parts. and bio nanoscience applications. The main interest of the present work is numerical and analytical investigation of heat transfer in MHD Jeffery-Hamel flow of a hybrid nanofluid with nanoparticle shapes (i.e., spherical, cylinder, and platelet) and mixture base fluid ( H 2 O - C 2 H 6 O 2 ( 50 % - 50 % )). Hybrid nanofluid containing alloys A A 7072 and A A 7075 as the nanoparticles is considered. The solution of the studied problem has been presented using a new analytical method (Daftardar-Jafari method). The obtained results in particular cases are compared to those gained by the HAM-based Mathematica package BVPh 2 and by the Runge–Kutta-Fehlberg 4th–5th order (RKF-45) for validation. The effect of diverse parameters for instance is as follows: external magnetic field H a ∈ 0 - 500 , Reynolds number R e ∈ 50 - 150 , opening of the channel α ∈ ± 2 ∘ - ± 6 ∘ , hybrid nanoparticles φ A A 7072 + A A 7075 ∈ 0 - 6 % , Hartmann number H a ∈ 0 - 150 , and nanoparticle shapes (i.e., spherical, cylinder, and platelet) on dimensionless velocity and temperature profiles, as well as on the behavior of skin friction coefficient and Nusselt number. The results indicate that the skin friction coefficient and Nusselt numbers decrease with the increasing nanoparticle shapes. In addition, the study's findings were found to be in exceptional agreement with existing literature results. [ABSTRACT FROM AUTHOR]
