Entropy generation effects on hydromagnetic Williamson nanofluid flow through a porous media

Abstract

In the present study, a hydromagnetic Williamson nanofluid passed through a stretching sheet embedded in a porous media is being analyzed by assuming the impact of thermal radiation and magnetic field on the flow properties. Previously, many researchers have studied nanofluid flow, but hydromagnetic Williamson nanofluid passed through a stretching sheet embedded in a porous media will be a new finding among all researchers. Our objective is to study a hydromagnetic Williamson nanofluid passed through a stretching sheet embedded in a porous media is being analyzed by assuming the impact of thermal radiation and magnetic field on the flow properties. By using appropriate similarity transformation the governing equations with boundary conditions were converted into a dimensionless form. The derived ordinary differential equation was solved using Spectral local linearisation method. The outcomes indicate that velocity reduces with increase in Williamson, Porosity and Magnetic field parameters, whereas the concentration profile improves with these parameters. Entropy generation rate is also enhanced when the Reynolds number, concentration difference parameter and Brinkman number are increased. The results have been validated with existing research and our results are found to be in excellent agreement. The study finds that good agreement is achieved.
