A comprehensive study of magnetohydrodynamics (MHD) hybrid copper-alumina nanofluid flow towards a permeable stretching sheet embedded in porous medium is analyzed analytically. The problem mathematical modeled into nonlinear partial differential equations, which are reduced ordinary equations via similarity transformation. analytical solutions for momentum and energy found. effects the porosit...

Unsteady permeable stretching sheet; Second grade fluid; Stagnation point flow; Heat transfer Abstract This article discusses the stagnation-point flow of second grade fluid over an unsteady stretching surface in the presence of variable free stream. Flow analysis has been carried out with heat transfer analysis. The resulting partial differential equations have been converted into ordinary dif...

The steady two-dimensional flow and heat transfer over a stretching/shrinking sheet in a nanofluid is investigated using Buongiorno's nanofluid model. Different from the previously published papers, in the present study we consider the case when the nanofluid particle fraction on the boundary is passively rather than actively controlled, which make the model more physically realistic. The gover...

An analysis has been carried out to study the flowandheat transfer in a liquid filmover a permeable stretching sheet.Using similarity transformations, the time-dependent boundary layer equations are reduced to a set of nonlinear ordinary differential equations. The resulting parameter problem and velocity as well as temperature fields are solved using the homotopy analysis method (HAM). Analyti...

The problem of magnetohydrodynamics boundary layer flow and heat transfer on a permeable stretching surface in a second grade nanofluid under the effect of heat generation and partial slip is studied theoretically. The Brownian motion and thermophoresis effects are also considered. The boundary layer equations governed by the PDE’s are transformed into a set of ODE’s with the help of local simi...
