EMHD Flow of Carbon-Based Nanofluids over a Plane Sheet with Rotation and Soret Effect

In this paper, Electro-Magneto-Hydrodynamic flow of carbon-based nanofluids over a plane sheet is investigated. Carbon nanotubes, graphene and graphite nanon- particles are considered with water as the base fluid. The governing equations formulated for the nanofluids are reduced to nonlinear ordinary differential equations by using similarity transformations. The coupled nonlinear equations are solved numerically by forth order Runge-Kutta method coupled with shooting techique. The numerical results obtained for the skin friction coefficient, nusselt number and sherwood number, as well as the velocity, temperature and concentration profiles for different values of various parameters demonstrate good agreement with literature. The enhanced thermal transport in graphene makes it a good coolant as compared to carbon nanotubes and graphite nanofluids.
