The influence of the Hall effect on the linear marginal stability of a molecular hydrodynamic Taylor-Couette flow in the presence of an axial uniform magnetic field is considered. The Hall effect leads to the situation that the Taylor-Couette flow becomes unstable for any ratio of the angular velocities of the inner and outer cylinders. The instability, however, does not exist for both signs of...

The purpose of this research is to study the problem mixed convection stagnation-point flow on a vertical stretching sheet with external magnetic field, effect radiation taken into account. partial differential equations are reduced ordinary using similarity transformation. transformed boundary layer then solved numerically via bvp4c in MATLAB software. effects different values parameter and Ha...

The effect of chemical reaction on an unsteady magneto hydrodynamic flow past an infinite vertical porous plate with variable suction and heat convective mass transfer, where the plate temperature oscillates with the same frequency as that of variable suction velocity. The non – linear partial differential equations governing the flow have been solved numerically using finite difference method....

The involvement of non-linear convection effects in a natural convective fluid flow and heat transfer along with the magnetic field porous cavity is studied numerically. Cu-water filled higher temperature at left wall lower right wall. governing equations are organized to achieve required by using two-dimensional energy, continuity momentum. Vorticity-stream function based dimensionless solved ...
