“…Choi et al (2001) observed that the thermal conductivity increases up to two times when small amount (less than 1 % by volume) of nanoparticles is added to the ordinary fluids. There is a vast amount of literature on the flow of nanofluid model proposed by Buongiorno (2006), but we are referring a few recent studies [Rana and Bharava (2012); Alsaedi and2009) ;Muthtamilselvan et al (2010) and Ahmad et al (2011) on different flow fields.…”

The aim of this paper is to study the effects of radiation absorption and chemical reaction on MHD free convection heat transfer flow of a nanofluid bounded by a semi-infinite flat plate in a rotating frame of reference. The plate is assumed to oscillate in time with steady frequency so that the solutions of the boundary layer are the similar oscillatory kind. The entire system rotates about the axes normal to the plate. The dimensionless governing differential equations for this investigation are solved analytically using perturbation method. The effects of various important parameters entering into the problem on velocity, temperature, skin friction and Nusselt number within the boundary layer are discussed for Cu-water-based nanofluid with the help of graphs. The predicted consequences obviously point out that the presence of nanoparticles in the base fluid improves the heat transfer process significantly. The results also show that the values of Nusselt number in case of nanofluid are more pronounced than that of micropolar fluid.

“…They observed that the similarity solution for the steady stagnation-point flow over an exponentially stretching/shrinking sheet is larger than compared with the linear stretching/shrinking sheet case solution. Rana and Bhargava [38] investigated laminar boundary layer fluid flow which results from the non-linear stretching of flat surface in a nanofluid with a finite element method. Heat generation/ absorption effects arise in many thermo fluid processes including cooling of electronic equipment, hot spot/sink modification of polymer manufacture, cooling/heating of plastic products etc.…”

This paper numerically investigates radiative magnetohydrodynamic mixed convection boundary layer flow of nanofluids over a nonlinear inclined stretching/shrinking sheet in the presence of heat source/sink and viscous dissipation. The Rosseland approximation is adopted for thermal radiation effects and the Maxwell-Garnetts and Brinkman models are used for the effective thermal conductivity and dynamic viscosity of the nanofluids respectively. The governing coupled nonlinear momentum and thermal boundary layer equations are rendered into a system of ordinary differential equations via local similarity transformations with appropriate boundary conditions. The non-dimensional, nonlinear, well-posed boundary value problem is then solved with the Keller box implicit finite difference scheme. The emerging thermo-physical dimensionless parameters governing the flow are the magnetic field parameter, volume fraction parameter, power-law stretching parameter, Richardson number, suction/injection parameter, Eckert number and heat source/sink parameter. A detailed study of the influence of these parameters on velocity and temperature distributions is conducted. Additionally the evolution of skin friction coefficient and Nusselt number values with selected parameters is presented. Verification of numerical solutions is achieved via benchmarking with some limiting cases documented in previously reported results, and generally very good correlation is demonstrated. This investigation is relevant to fabrication of magnetic nanomaterials and high temperature treatment of magnetic nano-polymers.
