The present study investigated the flow and heat transfer at a stagnation point past a stretching sheet. The premium silver nanoparticles Ag and economic alumina nanoparticles Al 2 O 3 suspended in water to form Ag-Al 2 O 3 /Water hybrid nanofluid are numerically examined. The analysis started with transforming the mathematical model which is in non-linear partial differential equations to a more convenient form by similarity transformation approach before being solved numerically using the Runge-Kutta-Fehlberg (RKF45) method. The characteristics and effects of the stretching parameter, conjugate parameter and the nanoparticle volume fraction for Al 2 O 3 and Ag on the variation of wall temperature, heat transfer coefficient and reduced skin friction coefficient are analyzed and discussed.
