The present Book deals with the heat transfer on hydromagnetic nanofluid flow past a stretching sheet/cylinder. The governing boundary layer equations of the fluid are transformed to ordinary differential equations by utilizing suitable similarity transformations. The reduced non-dimensional governing flow equations are solved by the Runge-Kutta method with shooting technique. This method is proved to be very effective in several areas of investigation and applications. This Book consists of two chapters. In the first chapter deals with Cattaneo-Christov heat flux on hydromagnetic and chemically reacting nanofluid flow across a stretching sheet. The second chapter has been focused on Hydromagnetic analysis on steady radiative nanofluid flow along a cylinder.
