Thermo-fluidic significance of non Newtonian fluid with hybrid nanostructures

Abstract

The main purpose of this investigation is to analyze the flow and heat transfer behavior of a non Newtonian fluid (Oldroyd B fluid) with hybrid nanostructure subject to externally inclined magnetic field. Cattaneo Christov heat flux model is incorporated in the energy equation. Non linear thermal radiation and viscous dissipation mechanisms are considered. Shooting technique is implemented to accomplish the numerical solution. The outcomes of the numerical computations are discussed with the aid of relevant graphs. The performed study reveals that rise in magnetic field strength shows opposite behavior to fluid velocity and temperature. Thermal relaxation time factor controls the rate of heat transportation. Rise in curvature parameter accelerates the fluid flow while that of angle of inclination of magnetic field imparts the reverse effect.
