Title STUDY OF DARCY FORCHHEIMER FLOW OF HYBRID NANOFLUID DUE TO A STRETCHING SHEET

Author(s) Maryam Irshad

Abstract The hybrid nanofluids have shown to be more valuable for heat transfer in engineering applications, according to recent breakthroughs in the field due to their improved thermophysical properties. Hybrid nanofluids provide improved efficiency in applications like solar collectors, automotive engines, electronic devices, solar heating, cooling in buildings, drug reduction and refrigeration because of their better heat transfer properties. Hybrid nanofluids may reduce environmental impact and save energy by increasing the efficiency of thermal systems. The current study examines the flow of electrically conducting hybrid nanofluid in a Darcy Forchheimer porous medium. The hybrid nanofluid is flowing towards an exponentially stretching sheet and the flow is significantly influenced by the presence of thermal radiation, MHD, mixed convection and Joule heating. The consideration of the various effects and the governing equations lead to a set of partial differential equations. The partial differential equations are reduced into a set of ordinary differential equations with the help of the appropriate similarity transformations. These equations are solved using the bvp4c technique in MATLAB software. The study provides the influence of the various parameters such as nanoparticle volume fractions, suction/injection parameter, magnetic parameter, Forchheimer number, Eckert number, porosity parameter, mixed convection parameter and radiation parameter. The outcomes of the associated parameters for velocity, temperature profile, skin friction coefficient and Nusselt number are presented in graphical form. The mixed convection parameter enhances the velocity profile. The heat generation/absorption parameter, magnetic parameter, porosity parameter, Forchheimer number, radiation parameter and Eckert number increases the temperature profile. The results yields from the current study are useful for the use of hybrid nanofluids in engineering, technology and many other fields.
