MHD Three-Dimensional Stagnation-Point Flow and Heat Transfer of a Nanofluid over a Stretching Sheet
In this study, the three-dimensional magnetohydrodynamic (MHD) boundary layer of stagnation-point flow in a nanofluid was investigated. The Navier–Stokes equations were reduced to a set of nonlinear ordinary differential equations using a similarity transform. The similarity equations were solved for three types of nanoparticles: copper, alumina and titania with water as the base fluid, to inve...
متن کاملNumerical and Series Solutions for Stagnation-Point Flow of Nanofluid over an Exponentially Stretching Sheet
This investigation is concerned with the stagnation-point flow of nanofluid past an exponentially stretching sheet. The presence of Brownian motion and thermophoretic effects yields a coupled nonlinear boundary-value problem (BVP). Similarity transformations are invoked to reduce the partial differential equations into ordinary ones. Local similarity solutions are obtained by homotopy analysis ...
متن کاملThe Magnetohydrodynamic Stagnation Point Flow of a Nanofluid over a Stretching/Shrinking Sheet with Suction
The magnetohydrodynamic (MHD) stagnation point flow of a nanofluid over a permeable stretching/shrinking sheet is studied. Numerical results are obtained using boundary value problem solver bvp4c in MATLAB for several values of parameters. The numerical results show that dual solutions exist for the shrinking case, while for the stretching case, the solution is unique. A stability analysis is p...
متن کاملStagnation-Point Flow of a Nanofluid Over a Nonlinear Stretching Sheet
Submitted: May 15, 2013; Accepted: Jun 23, 2013; Published: Jul 22, 2013 Abstract: Stagnation-point flow of a nanofluid over a nonlinear stretching sheet is investigated theoretically when the sheet is stretched with a power law velocity under a constant wall temperature. The governing nonlinear problem incorporates the effects of Brownian motion and thermophoresis is transformed by using appro...
متن کاملStagnation-point flow over a stretching/shrinking sheet in a nanofluid
An analysis is carried out to study the steady two-dimensional stagnation-point flow of a nanofluid over a stretching/shrinking sheet in its own plane. The stretching/shrinking velocity and the ambient fluid velocity are assumed to vary linearly with the distance from the stagnation point. The similarity equations are solved numerically for three types of nanoparticles, namely copper, alumina, ...
