The problem of boundary-layer flow and heat transfer of a non-Newtonian power-law fluid over a
moving porous infinite flat plate in the presence of viscous dissipation and heat generation or absorption
is investigated analytically. It is assumed that both the momentum and the energy equations
are coupled by the stress friction factor, and an assumption is introduced regarding the heat-transfer
index. It is found that exact analytical solutions for velocity and temperature exist only for pseudoplastic
fluids in the presence of suction at the surface. The effects of the suction parameter, Eckert
number, and the heat generation or absorption parameter on the velocity and temperature profiles,
as well as on the skin-friction coefficient and Nusselt number are discussed.
