| 總結: | In this research, the problem of stagnation point flow of hybrid nanofluids over stretching/shrinking sheet with heat source/sink impacts, as well as constant wall temperature is presented. The governing partial differential equations are transformed into nonlinear ordinary differential equations by applying suitable similarity transformations. These equations are then solved numerically using the Runge– Kutta–Fehlberg (RKF) method for some related parameters. For this research, the water-based nanofluid is considered with five types of nanoparticles: copper (Cu), alumina (A1₂O₃), silver titania (TiO₂) and iron (Fe₃O₄). The numerical solutions on the skin friction coefficient, (Cf Rex ½), Nusselt number, Nux Rex-½, velocity profiles, f'(η) and temperature profiles θ(η) influenced by the shrinking parameter, λ , the heat sink parameter, β , the first nanoparticle volume fraction, ф₁ and the second nanoparticle volume fraction, ф₂ are graphically displayed and discussed in more details. As a result, skin friction coefficient, Cf Rex ½ decreases while heat transfer rate, Nux Rex-½ increase for all combinations of hybrid nanofluids when stretching/shrinking parameter, (λ >0, λ <0) increase. |
