This laminar fluid study investigates the effects of a magnetic field on the entropy generation
during fluid flow and heat transfer due to an exponentially stretching sheet. Using the
suitable transformations we have obtained the analytical solutions for momentum and
energy equation in terms of Kummer's function. The velocity and temperature profiles are
obtained for various physical parameters which are utilized to find the entropy generation
number Ns and the Bejan number Be. The effects of various parameters on entropy …
This laminar fluid study investigates the effects of a magnetic field on the entropy generation during fluid flow and heat transfer due to an exponentially stretching sheet. Using the suitable transformations we have obtained the analytical solutions for momentum and energy equation in terms of Kummer's function. The velocity and temperature profiles are obtained for various physical parameters which are utilized to find the entropy generation number Ns and the Bejan number Be. The effects of various parameters on entropy production number and the Bejan number are studied through graphs using velocity and temperature profiles. © 2013 Wiley Periodicals, Inc.
