Abstract: The effects of variable viscosity and thermal
conductivity on fluid flow squeezed between two rotating disks in the presence
of a magnetic field are studied in this paper. A numerical solution of the
system, describing the problem under consideration is obtained and the effects
of viscosity parameter e and conductivity
parameter g, Prandtl number Pr
and Eckert number Ec on the flow field
are examined. It also examined the load capacity and friction torque which
change with e, the rotational
Reynolds number the
squeeze Reynolds number the
magnetic force parameters and the
relative angular velocity of the two disks S
and the Batchelor number Bt. In all
the previous studies, the viscosity and thermal conductivity are assumed to be
constant. But our result shows that the flow pattern is influenced by the
parameters e, g, Pr
and Ec.
Keywords and phrases: variable viscosity, variable thermal conductivity, viscosity parameter, conductivity parameter, liquid film.
