“…Chakraborty et al (2016) obtained numerical solution with convective boundary conditions for bio convection of a nanofluid flow. Extensive discussion of other applications recently studied by several researchers over stretching sheet which includes Sisko fluid flow employing Homotopy Analysis Method (HAM) Khan and Shahzad (2012), Second grade MHD fluid flow using Runge-Kutta (RK) sixth order integration scheme Das et al (2016), considered semi-infinite inclined and ideally transparent flat plate embedded in a porous medium with an Implicit finite difference scheme (IFDM), mixed convective couple stress fluid flow in a vertical channel with HAM by Kaladhar and Srinivasacharya (2014) and Prandtl-Eyring fluid flow with Keller-Box Method (KBM) Hussain et al (2017). Further a significant amount of research on Newtonian and non-Newtonian fluid flows over stretching sheet were found in (Akbar et al, 2016;Kumar et al, 2017;Chamkha et al, 2010;Reddy and Gorla, 2017).…”

This paper numerically investigates the magnetohydrodynamic boundary layer convective flow of an electrically conducting fluid in the presence of buoyancy ratio, heat source, variable magnetic field and radiation over an inclined nonlinear stretching sheet under convective surface boundary conditions. The Rosseland approximation is adopted for thermal radiation effects and the non-uniform magnetic field applied in a transverse direction to the flow. The coupled nonlinear momentum, thermal and species concentration governing boundary layer equations are rendered into a system of third order momentum and second order energy and mass diffusion ordinary differential equations via similarity transformations with appropriate boundary conditions. The nonlinear, non-dimensional, well-posed boundary value problem is then solved with the implicit finite difference scheme known as Keller Box Method. A detailed study of the influence of the emerging dimensionless parameters governing the flow on velocity, temperature and concentration distributions is conducted. Also the evolution of skin friction coefficient, Nusselt number and Sherwood number values are depicted graphically. Numerical results are validated with some limiting cases documented in previously testified results, and good correlation is confirmed. This investigation is relevant to the delineation of space, astrophysical plasmas, polymer processing and extrusion of rubber and plastic sheets.

A numerical computation has been carriedout for the steady, mixed convective, incompressible, viscous, electrically conducting couple stress fluid through a vertical plate with variable fluid properties in a porous medium. A uniform magnetic field is applied in the transverse direction and parallel to the vertical plate of the physical model and governing equations are derived for it."Using a suitable similarity transformation, governed PDE's are transformed into a set of ODE's which are highly non-linear coupled equations. An advanced Shooting technique is adopted to compute the variations of velocity, temperature, concentration in terms of non-dimensional parameters. Also physical interpretation of non-dimensional parameters like couple stress parameter magnetic field Prandtl number Schmidt number thermal conductivity and solutal diffusivity parameters are examined through plots for both variable permeability and uniform permeability."From the numerical results, an excellent agreement has been observed for the present results, as well as comparison is made between the present and the earlier works for a particular case of the problem.

“…Srinivasacharya and Kaladhar (2012a) analyzed Hall and Ion-Slip effects on mixed convection flow of couple stress fluid between parallel vertical plates. Later Kaladhar and Srinivasacharya (2014) established the effects of thermal and also solutal stratification on free and forced convection flow over a vertical plate flooded with couple stress fluid. Srinivas and Ramana Murthy (2015) analyzed and discussed thermodynamic MHD flow of two immiscible micropolar fluid between two parallel plates.…”

The present analysis is focused on free convective heat and mass transfer characteristics of magneto-nanofluid flow through a moving vertical plate in the presence of thermal radiation and thermal diffusion. The water-based nanofluid containing copper is taken into consideration. A uniform magnetic field is applied perpendicular to the plate. The governing equations are solved by applying finite difference method. Numerical results of the fluid velocity, temperature, concentration, shear stress, rate of heat transfer and rate of mass transfer are presented graphically for different values of the physical parameters encountered in the problem. It is noticed that the fluid velocity increases with increasing values of radiation parameter and Soret number. An increase in radiation parameter and solid volume fraction leads to enhance the fluid temperature. Rising values of Soret number serves to improve the species concentration. Increasing values of Schmidt number enhanced the shear stress at the plate but a reverse trend is found in the case of Soret number. The current study is well supported by the verification of a previous result.
