“…The transport andthermal properties of the base fluid are converted by nanoparticles. Bhaskar Chandra Sarkar et al [4] revealed that unsteady primary flow Hall current leads to a decrease in the amplitude of the shear stress. Lee et al [5] experimentally inspected the thermal conductivity performance of dilute nanofluids by a transient hot-wire technique.…”

The effects of convective heat generation and the oscillatory motion of a plate in the presence of MHD, Alumina nanofluid flow, thermal radiation, and Hall current are considered. The plate oscillates harmonically in its axes with uniform temperature. The dimensional equations have to be changed into non-dimensional equations with a set of dimensionless parameters. The Laplace transformation technique is utilized to get an exact solution. The possessions of velocity and temperature are analyzed with several parameters like Prandtl number (Pr), Grashof number (Gr), Hall parameter (m), magnetic parameter (M), radiation (R), solid volume fraction(ᵠ), phase angle(ω).The influence of primary and secondary velocity is discussed by the graph. It is observed that the increment of Hall parameter (m) diminishes the primary velocity, an increment of Grashof number leads to an increase in both velocities, and increasing solid volume fraction raises the temperature. The Nusselt number and skin friction coefficient values have expressed in the table. It is apparent that an increment of radiation increased the value of the Nusselt number and also an increment of phase angle value diminished the skin friction coefficient value.

The effects of heat and mass transfer on the flow of an oscillatory convective MHD channelflow of an electrically conducting viscous incompressible fluid in a slip flow regime in the presence of Hall current and thermal radiation are studied. A magnetic field of uniform strength is applied normal to the plates of channel. The two vertical porous plates of the channel are subjected to a constant injection/suction. The entire system rotates about an axis normal to the plates with a uniform angular velocity  . A closed form analytical solutions to the equations governing the fluid motion are obtained for the velocity, temperature and concentration fields. The numerical calculations for the velocity, temperature and concentration fields, and the coefficient of skin friction, rate of heat and mass transfer at the plates are performed. The results are presented graphically for different values of the physical parameters involved. It is seen that primary fluid flow is retarded due to angular velocity of the system.
