Assume that the plate has a surface temperature and concentration and is placed in a quiescent fluid of uniform ambient temperature and concentration (see Figure 1). A variable magnetic field is applied normally to the stretching sheet surface and the induced magnetic field is negligible. This can be justified for MHD flow at small magnetic ...

Let us consider an incompressible, two-dimensional viscous ferromagnetic dusty liquid flow over a stretchable surface. The sheet is taken toward x-axis with velocity u w normal to y-axis (see Fig. 1).A magnetic dipole is situated at a distance "a" from the sheet with its centre on y-axis.The direction of the magnetic dipole in the positive x-direction …

Magnetic Levitation of Pyrolytic Graphite. Pyrolytic carbon is a material similar to graphite, but with some covalent bonding between its graphene sheets as a result of imperfections in its production. Pyrolytic carbon is man-made and is not thought to be found in nature. Generally it is produced by heating a hydrocarbon nearly to its decomposition …

Magneto-Rheological (MR) Fluids consist of magnetic (typically iron) particles in a carrier fluid. In the presence of a magnetic field, the micron-sized particles link (see Figure 1 on the left, below) and change the fluid to a semi-solid in milliseconds. When the magnetic field is removed, the fluid just as quickly reverts back to its natural ...

Figure 1 describes the stretching surface of a sheet taken along the x and y axes, normal to the surface. Fluid flow occurs when y ≥ 0, which is triggered when the sheet is stretched out of the slit occurring at the origin (when x = y = 0). The flow speed at any arbitrary point on the plate is assumed to be proportional to the power of its distance from …

In controlling momentum and heat transfers in the boundary layer flow of different fluids over a stretching sheet, applied magnetic field may play an important role (Turkyilmazoglu, 2012). Kumaran et al. (2009) investigated that magnetic field makes the streamlines steeper which results in the velocity boundary layer being thinner. The heat ...
