A revised model of "Steady laminar natural convection of nanofluid under the impact of magnetic field on two-dimensional cavity with radiation" [AIP advances 9, 065008 (2019); https://doi.Org/10.1063/1.5109192]

ABSTRACT
This discussion exhibits the major scientific errors on the recent published paper, entitled "steady laminar natural convection of nanofluid under the impact of magnetic field on two-dimensional cavity with radiation" and their corrections indifferently. In Saleem at al. [1], the authors stated in both of abstract and problem assumptions that the non-Darcy model is used for the porous medium, while the porous terms are incompatible with this assumption. In addition, the authors used a non-inclined geometry in their investigation, but the governing equations are conflicting with this hypothesis. Further, the used range of the Darcy number Da is between 10-2 - 10-2 and this range is very large and did not represent the porous media flow. All of these observations make the mathematical formulations and the obtained results of Saleem at al. [1] are wrong. In the following sections, these scientific errors and their corrections will be presented minutely.
