Comment on “Heat transfer in MHD viscoelastic boundary layer flow over a stretching sheet with thermal radiation and non-uniform heat source/sink”, M.M. Nandeppanavar, K. Vajravelu & M.S. Abel [Commun Nonlinear Sci Numer Simulat 16 (2011) 3578–3590]

Two discrepancies are discovered in the paper of Nandeppanavar et al. (2011) [1]. First, the homogeneous solution for the temperature field is incorrect. Moreover, only one of the two homogeneous solutions that decay exponentially in the far field is presented; since two such solutions are available, a discussion of the selection process is needed. Second, the particular solution of the inhomogeneous energy equation is incorrect. These solutions are corrected and new tabulated results for the PST and PHF thermal problems are presented.
