  This article deals with study of the steady flow and heat transfer
characteristics of Sisko fluid over a rotating infinite disk. The flow and heat
transfer aspects are thoroughly investigated encompassing highly shear
thinning/thickening Sisko fluids. The modeled boundary layer equations are
reduced to a system of nonlinear ordinary differential equations using the
appropriate transformation. The resulting equations are then solved numerically
by shooting method in the domain . The numerical data for the velocity and
temperature fields are graphically sketched and effects of the relevant
parameters are discussed in detail. In addition, the velocity gradients at the
disk surface and the local Nusselt number for different values of the
pertaining parameters are given in tabulated form. Further, the flow and
temperature fields of power-law and Newtonian fluids are also compared with
those Sisko fluid. Moreover, a comparison with previously published work, as a
special case of the problem, has been provided and the results are found to be
in excellent agreement.
