Szukana fraza: [Abstract = "An unsteady flow and melting heat transfer of a nanofluid over a stretching sheet was numerically studied by considering the effect of chemical reaction and thermal radiation. The governing non\-linear partial differential equations describing the flow problem are reduced to a system of non\-linear ordinary differential equations using the similarity transformations and solved numerically using the Runge\-Kutta\-Fehlberg fourth\-fifth order method."]
