“…From Figures. 8-9, It is identified that an escalating of Γ and Ω causes a decrease and an increase in velocity and angular velocity respectively, which is analogous with the recorded consequences of Rup and Nering [16], Nering and Rup [17]. Micropolar Parameter, Γ, has much influence on the velocity field than Micro-inertia parameter, Ω.…”

“…Rahman et al [15] measured how much-differentiated heat generation and electric conductivity affect micropolar fluid and also elaborated their outcomes, taking the variable fluid viscosity along with variable thermal conductivity into account. Another worth noting approach was addressed by Rup and Nering [16] to scrutinising three water-based nanofluids (TiO2, Al2O3, and Cu), occupying the diameter approximately 10-38.4 nm, considering as single-phase fluids. On the other hand, an extended approach was also made by Nering and Rup [17], where water-based and ethylene-glycol mixed nanofluids were crucially utilised to determine the volume fraction solutions.…”

A mathematical framework has been designed to speculate the physical aspects of a binary chemical reaction (BCR) and Arrhenius activation energy (ACE) on magnetohydrodynamics Williamson micropolar nanofluid flow through a vertical stretching sheet. The fluid viscosity, electrical and thermal conductivity are presumed as reliant temperature function. Furthermore, the Lorentz force is deployed with an angle to the normal of the fluid flow. The natural transformations have been chosen to determine the non-dimensional regular expressions of the model. A conditionally stable finite difference analysis (explicit) is implemented to establish the computational analysis of the transfigured non-linear system of PDEs. The precision of the present numerical solution has been enriched by accomplishing analysis of stability as well as system convergence of finite difference analysis. The graphical representation, along with the tabular depiction, has been done for narrating the physical behaviour of important parameters extensively on various flow fields. The fluctuation of the boundary layer thickness is traced out with the assistance of streamlines, isotherms, and iso-concentration for the impression of the buoyancy ratio parameter and Lewis number. To draw perfection, achieved consequences of the current solution have been contrasted with some subsisting literature.

In this paper, effect of Hall currents on the thermal instability of couple-stress fluid permeated with dust particles has been considered. Following the linearized stability theory and normal mode analysis, the dispersion relation is obtained. For the case of stationary convection, dust particles and Hall currents are found to have destabilizing effect while couple stresses have stabilizing effect on the system. Magnetic field induced by Hall currents has stabilizing/destabilizing effect under certain conditions. It is found that due to the presence of Hall currents (hence magnetic field), oscillatory modes are produced which were non-existent in their absence.

“…Magneto-micropolar fluid with nano particles plays a vital rule in the view of its wide applications in many engineering problems such as electric transformers, heating elements and nano technology. Kazimierz et al [1] and [4] analyzed the unsteady natural convection in micropolar nano fluids, where the increasing heat exchange due to natural convection in water solutions of Al2O3, TiO2 and Cu with properties of micropolar nano-fluids in the vicinity of vertical plate heated by heat flux of q0 that rises suddenly. A vast investigation of convective heat transfer in nano-fluids by Buongiorno [2] predicted that the nano-particles' absolute velocity is roughly a sum of the base fluid velocity and the slip velocity.…”
