A REVISED MODEL OF "STEADY LAMINAR NATURAL CONVECTION OF NANOFLUID UNDER THE IMPACT OF MAGNETIC FIELD ON 2-D 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 2-D Cavity with Radiation" and their corrections indifferently. In Saleem et 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 is between 10–2-102 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 et al. [1] are wrong. In the following sections, these scientific errors and their corrections will be presented minutely.
