Unsteady free convection nanofluid flow near stagnation point of a three-dimensional body

Industrial systems gain a lot of benefit from unsteady free convection flow near the stagnation point of three-dimensional body such as the cooling of an infinite metallic plate in cooling baths and the boundary layer along material handling conveyers. In this study, a mathematical model of an unste...
