“…In the absence of magnetic parameter, Brownian motion and thermophoresis parameter, the present results are almost same with White (1991), Mohammadi et al (2012) and Khan and Pop (2013) as displayed in Table 2 Table 2, it is observed that the data produced by the present code and those of mentioned author's shows excellent agreement between two sets of data and, so justifies the use of the present numerical code for current model. …”

“…Hussein et al (2014) shown that the solid volume fraction has a significant influence on stream function and heat transfer, depending on the value of Hartmann and Rayleigh numbers. Khan and Pop (2013) noticed that the reduced Nusselt number is a decreasing function of each dimensionless number, while the reduced Sherwood number is an increasing function of higher Prandtl number and a decreasing function of lower Prandtl number for each Lewis number, Brownian motion and thermophoresis parameters. Haile (2015) analyzed the effects of various parameters on boundary layer nanofluid flow past a moving surface and obtained that the fluid flow and heat transfer are influenced by magnetic parameter, Brownian motion and thermophoresis parameter.…”

Abstract:In this work, the effects of dimensionless parameters on velocity field, thermal field and nanoparticle concentration field have been studied. In this regard, the governing partial differential equations are transformed into ordinary differential equations by using similarity transformations. These transformed equations are then solved numerically using the function bvp4c of MATLAB for different values of the parameters. The values of magnetic parameter have been considered as 0.0, 0.5, 1.0 & 1.5, stretching ratio as 0.0, 0.3, 0.5 & 0.7, Brownian motion as 0.0, 0.1, 0.15, 0.20, 0.3, 0.5, 0.8 & 1.5, and thermophoresis as 0.0, 0.05, 0.1, 0.14, 0.3, 0.6 & 1.0. The Prandtl number and Lewis number are taken as (1.0, 3.0 & 6.0) and (1.0, 2.0, 3.0 & 5.0 ) respectively. The results indicate that the velocity field increases for the increase in values of pressure gradient parameter, magnetic parameter and stretching ratio parameter. The temperature field decreases for the increase in values of stretching ratio parameter, Brownian motion parameter and Prandtl number but reverse result arises for the increase in values of thermophoresis parameter. The nanoparticle concentration field decreases for the increase in values of pressure gradient parameter, Brownian motion parameter andLewis number whereas it increases as thermophoresis parameter increases. Finally, for validity and accuracy, the present results has compared with previously published work and found to be in good agreement.

The present study analyzed numerically magneto-hydrodynamics (MHD) laminar boundary layer flow past a wedge with the influence of thermal radiation, heat generation and chemical reaction. This model used for the momentum, temperature and concentration fields. The principal governing equations is based on the velocity u w(x) in a nanofluid and with a parallel free stream velocity u e(x) and surface temperature and concentration. Similarity transformations are used to transform the governing nonlinear boundary layer equations for momentum, thermal energy and concentration to a system of nonlinear ordinary coupled differential equations with fitting boundary conditions. The transmuted model is shown to be controlled by a number of thermo-physical parameters, viz. the magnetic parameter, thermal convective parameter, mass convective parameter, radiation-conduction parameter, heat generation parameter, Prandtl number, Lewis number, Brownian motion parameter, thermophoresis parameter, chemical reaction parameter and pressure gradient parameter. Numerical elucidations are obtained with the legendary Nactsheim-Swigert shooting technique together with Runge–Kutta six order iteration schemes. Comparisons with previously published work are accomplished and proven an excellent agreement.
