An analysis is carried out to investigate the influence of variable thermal conductivity and partial velocity slip on hydromagnetic two-dimensional boundary layer flow of a nanofluid with Cu nanoparticles over a stretching sheet with convective boundary condition. Using similarity transformation, the governing boundary layer equations along with the appropriate boundary conditions are transformed to a set of ordinary differential equations. Employing Runge-kutta fourth-order method along with shooting technique, the resultant system of equations is solved. The influence of various pertinent parameters such as nanofluid volume fraction parameter, the magnetic parameter, radiation parameter, thermal conductivity parameter, velocity slip parameter, Biot number, and suction or injection parameter on the velocity of the flow field and heat transfer characteristics is computed numerically and illustrated graphically. The present results are compared with the existing results for the case of regular fluid and found an excellent agreement.

Abstract. The boundary layer heat and mass transfer flow of Casson nanofluid over a stretching sheet with constant wall temperature (CWT) under the magnetic field and thermal radiation effects is investigated numerically. Using similarity transformations, the governing equations are reduced to a set of nonlinear ordinary differential equations (ODEs). These equations are solved numerically by Shooting method. The effects of Casson parameter, magnetic parameter, porosity parameter, radiation parameter, Prandtl number, Brownian parameter and thermophoresis parameter on velocity, temperature and concentration fields are shown graphically and discussed. The results show that increase in Casson parameter causes the wall temperature increase well in the nanofluid.

“…Darcian drag force induces due to permeability of the porous medium and it plays a significant role in MHD free convection boundary layer flows because it modify the drag force arising from the magnetic field (Lorentz force). Ibrahim et al [2], Chaudhary and Jain [3], Postelnicu [4], Beg et al [6], Chamkha and Aly [10], Seth et al [11][12][13], Das [14], Khan et al [15], Prasad et al [16], Hossain et al [19], Balamurugan et al [20], Swetha et al [21] and Seth and Sarkar [23] investigated MHD free convection flow of an electrically conducting fluid in a porous medium considering different aspects of the problem. Rotating fluid system produces two types of forces, namely, Coriolis force and centrifugal force.…”

A mathematical analysis of unsteady MHD free convective flow of an incompressible, chemically reacting, electrically and thermally conducting fluid past an oscillating vertical plate embedded in a fluid saturated porous medium in a rotating system taking Hall and ion-slip currents into account is presented. The plate temperature is considered to be linear function of time for a certain time interval and thereafter it is kept at a constant temperature while species concentration at the surface of the plate is considered to be linear function of time. The governing coupled partial differential equations are solved by using Laplace transform technique. Two particular cases of interest are considered to obtain the solution of velocity field i.e. (i) when the natural frequency due to rotation and Hall current is different from the frequency of oscillations, and (ii) when the natural frequency due to rotation and Hall current is equal to the frequency of oscillations (i.e. the case of resonance). The expressions for skin friction, Nusselt number and Sherwood number are also derived. To analyze the flow features of the present problem the velocity, temperature and concentration distributions are depicted graphically whereas the skin friction at the plate, Nusselt number and Sherwood number are presented in tabular form for various values of different pertinent flow parameters.
