Joule heating and viscous dissipation in flow of nanomaterial by a rotating disk

This paper aims to analyze the flow of second grade nanoliquid by a rotating disk. Nanofluid under investigation strongly depends upon Brownian motion and thermophoresis. Heat transfer is studied subject to dissipation and Joule heating. Governing problems are made dimensionless. After this the out coming problems for momentum, temperature and concentration are solved. The convergence criteria related to solutions is spelled out. Convergence interval for solutions is analyzed. Impact of different variables on velocity, concentration and temperature is elucidated by plotting graphs. Velocity and temperature gradients are calculated and discussed. The obtained results demonstrate that velocity field enhances for larger estimation of viscoelastic variable. Further results also demonstrate that velocity gradient has opposite effects for Hartman number and viscoelastic parameter. Temperature gradient is more for higher estimation of Reynolds number.
