Effect of Hall Current on MHD Non-Newtonian Unsteady Casson Fluid Porous Rotating Disk Flow with a Uniform Electric Field

The effects of Hall current and a uniform electric field on non-Newtanian casson fluid porous rotating disk flow are examined. A uniform angular velocity, an axial uniform magnetic field and the Hall current are taken into considered. Examples of Casson fluid include jelly, tomato sauce , honey , soup and concentrated fruit juices, ect. Human blood can also be treated as Casson fluid. Considering the suitable similarity parameters the governing equations of the problem are then transformed into the non-linear ordinary differential equations. The ordinary similarity differential equations are then solved numerically by six order Runge-Kutta method and shooting method using the Nachtsheim- Swigert iteration technique.

A Note on the Induced Flow and Heat Transfer Due to a Deforming Cone Rotating in a Quiescent Fluid

This short brief is to address the boundary layer flow of motion due to a rotating as well as stretchable/shrinkable flexible cone in an otherwise still fluid. It is shown that the relevant information on the progress of the triggered boundary layer structure can be obtainable from the limiting traditional deformable rotating disk flow of von Karman, recently published in the literature. Thus, the physical parameters of great interest from the engineering point of view concerning a cone of a particular apex angle can be easily deduced as a multiplying factor corresponding to the deformable rotating disk flow.
