Transport of thermal energy in the magnetohydrodynamic oblique stagnation point flow in a hybrid nanofluid with nanoparticle shape effect

In the present paper, the augmented heat characteristics of a hybrid nanofluid which is a blend of Al2O3 (alumina) and Ag (silver) in the host hybrid fluid (C2H6O2‐H2O) (50%–50%) impinging obliquely on an elastic surface with magnetic lines of force are investigated. The properties of the nanofluid...

Description
Summary:In the present paper, the augmented heat characteristics of a hybrid nanofluid which is a blend of Al2O3 (alumina) and Ag (silver) in the host hybrid fluid (C2H6O2‐H2O) (50%–50%) impinging obliquely on an elastic surface with magnetic lines of force are investigated. The properties of the nanofluid are assessed through the computational solutions established with the aid of the popular Runge–Kutta–Fehlberg fifth‐order (RKF 5) numerical technique. Outputs of the analysis reveal that the rate of thermal energy transport in the hybrid (mono) nanofluid is enhanced by 11.5% (5.8%) by using blade‐shaped nanoparticles in comparison to that of the spherical particles. Stream contours of both nanofluids are inclined to the left (right) of the stagnation‐point for positive (negative) values of the stagnation flow parameter.
