Fluids remain effective for longer so fluid use is reduced. Contaminated fluid enters the inlet port where it is equally dispersed by the unique tapered radial flow channels. These channels slow the fluid down. Fluid then passes down the outside of the centrally mounted 'rare earth' magnetic core where contamination particles are removed.

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 ...

In progress of anti-shock characteristics of small size precision equipment, a miniaturized damper is required to have better damping characteristics. However, damping efficiency becomes less as damper size decreases, and so for compensation of its defect, a porous elastic sheet damper with a magnetic fluid is proposed. An analytical estimation …

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 ...
