This study is performed on the numerical investigation of electro-magnetohydrodynamic (EMHD) radiating fluid flow nature along an infinitely long vertical Riga plate with suction in a rotating system. The prevailing equations are generated from the Navier–Stokes’ and energy equations. A uniform suction velocity is introduced to control the flow. The prevailing boundary layer (BL) equations are the stuff to delineate the mechanical features of the flowing nature along with the electromagnetic device (Riga plate). Accordingly, the use of usual transformations on the equations transformed those into a coupled dimensionless system of non-linear partial differential equations (PDEs). After conversion, the elucidation of the set of equations is conducted numerically by an explicit finite difference method (FDM). The criteria for stable and converging solutions are constructed to find restrictions on various non-dimensional parameters. The retrieved restrictions are $$P_{r} \ge 0.19,\,$$ P r ≥ 0.19 , $$R_{d} \ge 0.1,\,\,$$ R d ≥ 0.1 , $$S \ge 1,$$ S ≥ 1 , $$E_{c} = 0.01\,\,$$ E c = 0.01 and $$0 < R \le 0.1$$ 0 < R ≤ 0.1 . Furthermore, sensitivity tests on mesh and time as well as comparison within the literature have been demonstrated in graphical and tabular form. Finally, the important findings of the non-dimensional parameters influences have been portrayed in graphical manner by using the MATLAB R2015a tool. A substantial uprise is noted for both the velocities (secondary and primary) under the rising actions of the modified Hartmann number, whereas the suction parameter suppresses both the velocities.

“…Babu and Satya Narayan [ 29 ] examined chemical reaction and thermal radiation effects on MHD convective flow in a porous medium in the presence of suction. Das [ 30 ] and Sivaiah [ 31 ] investigated studied the effect of chemical reaction and thermal radiation on heat and mass transfer flow of MHD micropolar aid in a rotating frame of reference. Convection problems associated with heat sources within fluid-saturated porous media are of great practical significance in geophysics and energy-related problems, such as recovery of petroleum resources, cooling of underground electric cables, storage of nuclear waste materials groundwater pollution, fiber and granular insulations, chemical catalytic reactors, and environmental impact of buried heat generating waste.…”

An analysis study is presented to study the effects of Hall current and Soret effect on unsteady hydromagnetic natural convection of a micropolar fluid in a rotating frame of reference with slip-flow regime. A uniform magnetic field acts perpendicularly to the porous surface which absorbs the micropolar fluid with variable suction velocity. The effects of heat absorption, chemical reaction, and thermal radiation are discussed and for this Rosseland approximation is used to describe the radiative heat flux in energy equation. The entire system rotates with uniform angular velocity Ω about an axis normal to the plate. The nonlinear coupled partial differential equations are solved by perturbation techniques. In order to get physical insight, the numerical results of translational velocity, microrotation, fluid temperature, and species concentration for different physical parameters entering into the analysis are discussed and explained graphically. Also, the results of the skin-friction coefficient, the couple stress coefficient, Nusselt number, and Sherwood number are discussed with the help of figures for various values of flow pertinent flow parameters.

Hall current, chemical reaction, and radiation results on transient magnetohydrodynamic flow past an inclined plate: FEM

This paper investigates the influence of Hall current, chemical reaction, and radiation on transient magnetohydrodynamics flow past an inclined plate. The basic nonlinear partial differential equations (PDEs) are converted to dimensionless nonlinear PDEs with similar transformations. The transformed flow equations are solved by the finite element method with appropriate initial conditions. The influence of physical parameters on velocities, temperature, as well as concentration dispensations is addressed computationally and demonstrated by graphs. The influence of flow parameters on skin-friction coefficients τ 1 and τ 2 are discussed and presented in the form of a table. Finally, a qualitative similarity was made between the present paper and the earlier published results and it was initiated that there is tremendous conformity between the results.
