Mixed convective magnetohydrodynamic flow of hybrid fluid with viscous dissipation: A numerical approach

Abstract

The aim of this analysis is to examine hybrid fluid (Ag + Cu/C12H26- C15H32) by a stretched surface. Flow is analyzed in the stagnation point region while a constant uniform magnetic field is implemented normally to the flow. Heat transfer analysis is explored by taking convective boundary, mixed convection, and viscous dissipation. Mathematical modeling (PDEs) of the physical problem is performed. These modeled PDEs are further reduced into ordinary differential equations (ODEs) by implementing adequate variables (transformations). To make the situation favorable, the first order system of ODEs is obtained from these ODEs and solved via the shooting technique and RK-4 method. Solutions are obtained graphically. The impact of different physical parameters on velocity, skin friction coefficient, temperature, and Nusselt number are visualized via bar graphs by considering all three fluids (basefluid (C12H26- C15H32), nanofluid (Ag/C12H26- C15H32), and hybrid fluid (Ag + Cu/C12H26- C15H32)) is noted. Comparison amongst basefluid (C12H26- C15H32), nanofluid (Ag/C12H26- C15H32), and hybrid fluid (Ag + Cu/C12H26- C15H32)) is visualized via pie charts. Higher magnetic parameter causes reduction in velocity profile while it is intensified by mixed convection and velocity ratio parameters. Temperature boosts with increment in Eckert number, thermal Biot number, magnetic and mixed convection parameters. Skin friction is controlled via higher mixed convection and velocity ratio parameters. Heat transfer is intensified by higher Eckert and thermal Biot numbers.
