Abstract

The entropy generation during hydromagnetic boundary layer flow of a viscous incompressible electrically conducting fluid due to radial stretching sheet with Newtonian heating in the presence of a transverse magnetic field and the thermal radiation has been analyzed. The governing equations are then solved numerically by using the fourth order Runge-Kutta method with shooting technique. The effects of the pertinent parameters on the fluid velocity, temperature, entropy generation number, Bejan number, as well as the shear stress at the surface of the sheet are discussed graphically and quantitatively. It is examined that because the presence of a magnetic field, the entropy generation in a thermal system can be controlled and reduced.
