“…Siddiqa and Hossain have examined the impact of the Hall current on boundary layer hydromagnetic free convective flow through a semi‐infinite heated vertical plate due to a strong magnetic field. Seth and Singh have analyzed the hydromagnetic combined (free as well as forced) convection flow of an incompressible, thermally, and electrically conducting viscous liquid through a rotating channel due to the Hall current. In another article, Khan et al discussed the heterogeneous and homogeneous reactions for hydromagnetic stagnation flow accompanied by Joule heating and viscous dissipation.…”

The fully developed laminar magnetohydrodynamic free convection between two concentric vertical cylinders with Hall currents and heat source/sink, in the presence of the radial magnetic field, are studied. The governing thermal energy and momentum equations are changed into ordinary differential equations whose solutions are determined in closed-form expressions of the Bessel and modified Bessel functions of order zero. A parametric investigation illustrating the impacts of the Hall current, magnetic field, heat source, and radii ratio has been accomplished graphically to examine the changes in temperature as well as velocity while the Nusselt number, mass flux, and skin friction values have been presented in tabular forms. The results ensure that the Hall current has a strong and direct impact on the flow character, such that the influence of the Hall parameter enhances the velocity fields in the appearance of heat source and sink. The velocity remains almost constant as the Hall parameter value is greater than four.Moreover, the velocity and temperature fields have an increasing tendency due to the heat source and inversely for the heat sink.

“…The influence of Hall current on the efficiency of an MHD generator was investigated by Sherman and Sutton [ 2 ]. Several authors [ 3 , 4 , 5 , 6 , 7 , 8 , 9 ] discussed the influence of Hall current on hydromagnetic flow problems for various aspects. Recently, Abdel-Wahed [ 10 ] examined the impacts of hall current on the MHD boundary layer flow and heat transfer of Ferro nanofluid in a curved tube.…”

The impacts of entropy generation and Hall current on MHD Casson fluid over a stretching surface with velocity slip factor have been numerically analyzed. Numerical work for the governing equations is established by using a shooting method with a fourth-order Runge–Kutta integration scheme. The outcomes show that the entropy generation is enhanced with a magnetic parameter, Reynolds number and group parameter. Further, the reverse behavior is observed with the Hall parameter, Eckert number, Casson parameter and slip factor. Also, it is viewed that Bejan number reduces with a group parameter.

“…Seth and Ansari examined the influence of the Hall current on buoyancy driven flow of a conducting fluid in a revolving channel. In another article, Seth and Singh investigated the effect of the Hall current on mixed convection flow of a viscous incompressible fluid in a rotating channel. They observed that in the presence of the Hall current, increase in rotation destabilizes the primary component of fluid velocity while the opposite is observed along the secondary direction.…”

The steady fully developed hydromagnetic flow of a viscous incompressible and electrically conducting fluid in a vertical microchannel has been studied taking into account the influence of Hall current, ion-slip effects and an induced magnetic field. Exact solutions for the governing equations responsible for the flow formation are obtained by the method of the undetermined coefficient and presented graphically. It is found that in the presence of the ion-slip effect, both primary and secondary components of fluid velocity increase with the Hall parameter for symmetric as well as asymmetric heating of the microchannel surfaces. Also, the magnetic field supports flow along the secondary flow direction while the reverse impact is observed along the primary flow direction.
