Therapeutic applications of Darcy-Forchheimer hybrid nanofluid flow and mass transfer over a stretching sheet

The purpose of the current study is to investigate the therapeutic applications of Darcy-Forchheimer flow and mass transfer of hybrid nanofluid (HNF) over a stretching sheet by the influence of magnetic field and chemical reaction. The HNF is the conglomeration of two types of NPs (NPs) copper (metal) and alumina (metallic oxide) with water as regular fluid. Copper NPs act as an anti-biotic, anti-microbial, and anti-fungal agent whereas alumina NPs has wide range of biomedical applications including cancer therapy, biosensing, and immunotherapy etc. Thus, the present model is useful because it may be used to a variety of fields, including biomedicine, microelectronics, biology, and industrial production processes. By introducing the similarity transformations, the governing partial differential equations (PDEs) are transformed into a set of nonlinear ordinary differential equations (ODEs) and then solved numerically with MATLAB bvp۴c code by varying numerous operating physical parameters. It is found that higher values of magnetic, Forchheimer and slip parameters decrease the velocity profiles. Slip parameter and chemical reaction parameter has opposite effect on concentration profile. Volume fractions of NPs and slip parameter have opposite effects on skin friction coefficient and Sherwood number.
