Effect of Inclined Magnetic Field on Unsteady Flow of Tangent Hyperbolic Nanofluid Over a Stretching Surface with Thermal Radiation

This paper reports an analysis of effect of inclined magnetic field on unsteady flow of tangent hyperbolic nanofluid over a stretching surface in the presence of thermal radiation. The tangent hyperbolic fluid model is used to characterize the non-Newtonian fluid behaviour. The system of governing partial differential equations of mass, momentum, energy and nanoparticle concentration is transformed into a system of ordinary differential equations using similarity transformations and then solved numerically using by the Runge-Kutta fourth order along with shooting technique. The flow features and the heat transfer characteristics and nano particle volume fraction are analysed and discussed in detail for several sets of values of the governing flow parameters and found that for the increased inclination, the rate of heat and mass transfer increased whereas a reverse trend is seen for unsteadiness. The effects of the various parameters on the velocity, temperature and concentration profiles are illustrated graphically and the results for the skin-friction coefficient, local Nusselt number and the local Sherwood number are presented.
