“…Magnetic fluids, liquids, metals, and mixtures containing water, salt and other electrolytes are examples of materials that can be investigated using MHD. Hannes Alfven was the first person to introduce the term MHD where a sequence of Navier-Stokes equations and Maxwell's equations was applied in MHD to understand the flow behaviour of a fluid with electromagnetic properties by Narender et al, [26]. Asimoni et al, [27] focused on MHD free convective flow of viscous incompressible electrically conducting fluid past a vertical plate and found that when magnetic field strength increases, the velocity of the fluid decreases for both cases.…”

This study focuses on the investigation of aligned MHD natural convection flow and heat transfer of a Casson nanofluid past a vertical plate with convective boundary condition. Casson nanofluid are found in a wide range of commercial and technological applications, including dissolved polymers, biological solutions, paints, asphalts, and glues. The governing partial differential equations (PDE) is transformed to ordinary differential equations (ODE) by using similarity transformation. Keller box method is employed to numerically solve the transformed partial differential equations and then the system is solved by Fortran programming. The results for both the velocity and temperature profiles of Casson nanofluid as well as the skin friction and Nusselt number that are affected by nanoparticles shape factor considering parameters aligned angle of magnetic, interaction of magnetic field, volume fraction of nanoparticles, Local Grashof number, Casson parameter and Biot number are presented graphically and in tabulated form. It is also found that the velocity increases while the temperature decreases when the aligned angle of magnetic, interaction of magnetic field, Casson parameter and Local Grashof number increase. The skin friction and Nusselt number increases for all parameters except for Casson nanofluid parameter. For convective boundary condition, Biot number increases when both velocity and temperature profiles increase. The nanoparticles shape of laminar has the highest velocity and temperature while the spherical shape has the lowest for all parameters.

Basha et al 23 gave the numerical approach to investigate the effects of the magnetic dipole on the Ferromagnetic deflation point flow of Carreau nanofluid for two different cases shear thickening or thinning via a porous plate and wedge.…”

The present article focuses on radiative hydromagnetic unallied stagnation point flow past a horizontal extending surface under varying viscosity concerning temperature. To understand the physical behaviour of the physical model, we converted the scheme of nonlinear partial differential equations to ordinary differential equations using suitable similarities. Matlab bvp5c procedure is adopted to obtain the computational outcomes. Also, we graphed the flow and temperature fields with and without the influence of magnetic field for various controlling non-dimensional parameters such as thermal radiation, variable viscosity, Prandtl number, velocity and temperature ratio parameters, etc. Moreover, Nusselt number and wall friction are evaluated and presented in the table for both criteria. It is noticed that the heat transfer rate is high in the presence of a magnetic field when compared to the absence of a magnetic field. Thermal radiation, viscosity variation, and temperature ratio parameters effectively stabilise the axial flow velocity.

An analysis of stagnation point flow of heat and mass transfer of double diffusive mixed-convective stream with radiating vertical plate and convective boundary conditions. The Runge-Kutta method with shooting procedure is used to solve the transformed equations mathematically. An accuracy of the numerical procedure has been validated through a restriction of the current work compared with prior available results. The shear surface stress, Nusselt and Sherwood number are increased with increase in Prandtl number. The Biot number Bi > 0.1 is investigated and observed that to increase the Prandtl number, the friction coefficient, Nusselt number and Sherwood number are increased. The impact of pertinent constraints on distinct flow parameters are determined and analyzed through tables and graphs.
