Main Article Content
The purpose of present article is to examine the influences of heat and mass fluxes in the magnetohydrodynamic (MHD) flow of Casson nanofluid by an exponentially stretching sheet. Formulation and analysis is presented when thermal radiation and viscous dissipation are taken into account. Transformation technique is adopted for the reduction of PDE systems to ODE systems. Both analytic and numerical solutions of dimensionless velocity, temperature and nanoparticle concentration fields are developed. The impacts of sundry parameters on the velocity, temperature and nanoparticle concentration profiles are plotted and discussed. The values of skin-friction coefficient are obtained numerically. It is found that an increase in the values of Casson parameter reduced the skin-friction coefficient while it enhances for larger Hartman number.
