Hydromagnetic Flow

 Hydromagnetic flow of an incompressible viscous nanofluid past a vertical plate in the presence of thermal radiation is investigated both analytically and numerically. The radiative heat flux is described by the Rosseland diffusion approximation in the energy equation. The governing non-linear partial differential equations are converted into a set of ordinary differential equations by suitable similarity transformations. The resulting ordinary differential equations are successfully solved analytically with the help of homotopy analysis method and numerically by the fourth order Runge–Kutta method with shooting technique. The effects of various physical parameters are analyzed and discussed in graphical and tabular forms. The effects of some physical parameters such as Lewis number, Prandtl number, buoyancy ratio, thermophoresis, Brownian motion, radiation parameter and magnetic parameter are analyzed on the velocity, temperature and solid volume fraction profiles as well as on the reduced Nusselt number and the local Sherwood number. An excellent agreement is observed between present analytical and numerical results. A nanofluid is a new class of heat transfer fluids that contains a base fluid and nanoparticles. The use of additives is a technique applied to enhance the heat transfer performance of base fluids. The nanofluid has many applications. For example, it is used as coolants, lubricants, heat exchangers, micro channel heat sinks and many others . The term ‘nanofluid’ was first proposed by Choi to indicate engineered colloids composed of nanoparticles dispersed in a base fluid. A comprehensive survey of convective transport in nanofluids was made by Buongiorno .The influence of nanoparticles on natural convection boundary layer flow over a vertical plate was considered by Kuznetsov and Nield .
