Özet:

 

The time varying Couette flow with heat transfer of a dusty  viscous incompressible electrically conducting fluid under the  influence of a constant pressure gradient is studied without  neglecting the Hall effect.  The parallel plates are assumed to be  porous and subjected to a uniform suction from above and injection  from below while the fluid is acted upon by an external uniform  magnetic field applied perpendicular to the plates.  The governing  equations are solved numerically using finite differences to yield the  velocity and temperature distributions for both the fluid and dust  particles.  It is found that both the fluid and the solid-particle  phases have 2 components of velocity.  The main 2 components of  velocity of the fluid and dust particles, u and up, respectively, are  found to increase with an increase in the Hall parameter m.  However,  the other 2 components of velocity w and wp, which result due to the  Hall effect, increase with the Hall parameter m for small m and  decrease with m for large values of m.  It is also found that the  temperatures of both fluid and particle phases decrease with the Hall  parameter m.
