“…Their findings showed that, an increase of magnetic field decreases the velocity distribution. Kalyani et al (2015) studied MHD mixed convection flow past a vertical porous plate in a porous medium with heat source/sink and soret effects. Their results showed that, the effect of magnetic field is to reduce the velocity profile.…”

This research examines the impact of suction/injection and permeability of porous materials on a steady natural convection Couette flow of a viscous incompressible fluid passing through a vertical porous plate. The dimensionless governing momentum and energy equations were solved exactly. Graphs were plotted to check the impact of the governing flow parameters and a table was plotted for comparison of the results. It was found from the investigation that, the fluid injection (λ>0) increases the fluid velocity and temperature distributions while the magnetic field (M) retards the fluid velocity. It is also noteworthy to mention that the suction (λ>0) reduces the fluid velocity and temperature distributions in the channel. The velocity profile is observed to increase with increase in the permeability (K) of the materials.

The features of two-dimensional immiscible laminar flow of micropolar nanofluid over an unstable stretching sheet with a predetermined surface heat flux are examined in this problem. The thermal boundary conditions have an impact on heat transfer properties. The similarity transformations are utilized to transfigure highly non-linear guided PDE into ODEs. Shooting technique is used to resolve these equations. There are several flow characteristics that are relevant to this issue, including the unsteadiness parameter (S), material parameter (m), viscosity (K), Prandtl number (Pr), Brownian motion parameter (Nb), and thermophoretic parameter (Nt). Graphs are used to study the impact of various flow parameters on liquid velocity, micropolar, temperature, and nonoparticle concentration profile. In order to obtain the findings for this problem, we used the tbvp4c Matlab programme. We noticed that velocity profile, thermal profile, microrotation of the particle, and nanoparticle concentration profile all diminish as an unsteady number S increasing, micropolar profile increases. With a rise in boundary parameter m, the micropolar fluid profile and the concentration of nanoparticle profiles are dropping while the velocity profile and temperature profile are rising. The temperature profile is rising while the volume fraction of nanoparticle is falling as the Brownian motion Nb increasing. The thermal profile and nanoparticle concentration profile both rise with an increase in the thermophoretic number Nt. With an increasing of magnetic field parameter M, the velocity profile and micropolar profile are declining, but the thermal and nanoparticle concentration profile is rising.

“…) and for medium molecular weight ( ), Soret effect is found to be of considerable magnitude such that it cannot be ignored. In view of these above-mentioned studies, the many researchers [15][16][17][18][19][20][21][22][23][24][25][26] have analyzed theoretically the Soret and Dufour effects in porous medium on heat-mass transfer for convective flow and they presented their numerical solutions with various effects of heat source / sink and suction / injection.…”

A theoretical investigation has been made for a radiating and chemically reacting viscous-fluid of a conducting gas over a vertical porous surface immerse in a saturated porous medium for the impact of magnetic drag-force, buoyancy forces and thermal-diffusion (Soret) order under oscillatory suction and heat absorption. The analytical solutions have been derived for the physical variables related to the governing equations under the appropriate boundary conditions. It is found that the velocity profiles increase with the increasing values of Soret number (S0) and higher Soret number (S0 = 5) shows the large temperature difference. It is noticed that increasing radiation parameter (R) elevated the velocity profiles near the plate. In the effects of Soret number (S0) the velocity profiles are an increasing function for both the cases of M = 0 and M = 10. The validity and accuracy of the flow model is presented and found suitable to proceed the work. In this study, the findings would be useful in many practical areas such as diffusion operations, which involved molecular diffusion of species with molar concentration.
