Magnetohydrodynamic and Heat Transfer Effects on the Stagnation-Point Flow of an Electrically Conducting Nanofluid Past a Porous Vertical Shrinking/Stretching Sheet in the Presence of Variable Stream Conditions
A steady two-dimensional magnetohydrodynamic stagnation-point flow of an electrically conducting fluid and heat transfer with thermal radiation of a nanofluid past a shrinking and stretching sheet is investigated numerically. The model used for the nanofluid incorporates the effects of the Brownian motion and thermophoresis. A similarity transformation is used to convert the governing nonlinear boundary-layer equations into coupled higher-order nonlinear ordinary differential equations. The result shows that the velocity, temperature, and concentration profiles are significantly influenced by the Brownian motion, heat radiation, and thermophoresis particle deposition
