MHD Darcy-Forchheimer Cu-Ag/H₂O-C₂H₆O₂ hybrid nanofluid flow via a porous stretching sheet with suction/blowing and viscous dissipation

Abstract

In this article, the combined impact of thermal radiation and suction/blowing on the MHD flow of Cu-Ag/H2O-C2H6O2 hybrid nanofluid through a stretchable surface in Darcy-Forchheimer porous medium is considered. The Cartesian coordinate system and boundary layer approximation are used in the mathematical modeling of governing equations. By using suitable transformation, the governing expressions are changed into the non-dimensional forms, which are solved employing Runge-Kutta-Fehlberg method. The physical significance of relatable parameters on flow and thermal fields are analyzed through graphs. The key outcomes include that velocity diminished for the case of suction and absence of suction/injection region, on raising the values of Forchhiemer, magnetic and porosity parameters. Moreover, for blowing region, dual behavior is noticed in velocity profiles with increase in Forchhiemer and porosity parameters.
