This study presents a problem of nanofluid stagnation point flow over a stretching/shrinking sheet with impacts from heat source/sink and constant wall temperature. By using appropriate similarity transformations, the governing partial differential equations are converted into nonlinear ordinary differential equations. The Runge-Kutta-Fehlberg (RKF) and shooting methods are then used to numerically solve these equations for the relevant parameters. In this study, three different types of nanoparticle copper Cu, alumina A1₂O₃, and titania TiO₂ are used in a water-based nanofluid. The numerical solutions for the skin friction coefficient Cf Rex ½, heat transfer rate Nux Rex ½, velocity profiles f'(η), and temperature profiles θ(η) affected by the stretching/shrinking parameter λ , the heat source/sink parameter β , and the nanoparticle volume fraction ф are graphically represented and further discussed.
