Comments on 'Importance of activation energy in development of chemical covalent bonding in flow of Sisko magneto-nanofluids over a porous moving curved surface'

摘要

Commentary is presented on Ahmad and Khan [1]'s paper, where the authors studied activation energy significance in development of bonding of chemical covalent in Sisko magneto-nanofluids flow past a porous curved moving surface. This commentary shows that there is no agreement in the D-B and D-T units employing the energy & concentration equations. (C) 2020 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
