Stagnation Point Flow of a Hybrid Nanofluid Under the Gravity Modulation Effect

The effectiveness of the heat transfer fluid in cooling or heating process determines optimal performance nuclear reactor, microelectronic devices, and chip production. Since thermal conductivity improved hybrid nanofluids, current study sought to investigate unsteady free convection nanofluid flow near a stagnation point as influenced by g-jitter. A consisted copper (Cu) alumina (Al2O3) nanoparticles, which were added into water form Cu-Al2O3/water was considered. Next, relevant variables transformed governing equation dimensionless equations before being solved numerically using centered implicit finite difference method. field discussed concerning curvature ratio. results showed that g-jitter effect caused fluctuation all profiles physical quantities. frequency amplitude reduced velocity profile while improving temperature distribution. rate increased 10.77% when nanoparticles volume fractions rose from 0.1 0.2. However, presence had thickness momentum boundary layer due an increase local skin friction.
