摘要

This communication aims to report the corrections to HAM results presented in a paper by Chotbi [1]. The graphical results presented by Chotbi are observed to be divergent as a consequence of the bad selection of the values of auxiliary parameter h. Further, the results presented by Ghotbi do not agree with the exact solution for η ≥ 2.5. We present highly accurate and convergent HAM solutions which is in good agreement with the exact solution for the entire spatial domain 0 ≤ η < ∞. A comparison between the present HAM solution and the exact solution has been reported and both the solutions are found to be in good agreement.
