Entropy Generation in Magnetohydrodynamic Radiative Non-Newtonian Dissipative Convection Flow From an Inclined Plane: Numerical Study

A theoretical model is developed to study entropy generation in non-Newtonian thermal convection from an inclined plate as a simulation of electroconductive polymer materials processing of relevance to automotive coating applications. High invokes radiative effects which are analysed with the Rosseland diffusion flux . The Jeffery’s viscoelastic model is deployed to describe the non-Newtonian of the fluid and provides a good approximation for magnetic polymers, which a novelty of the present work. The normalized nonlinear boundary value problem solved computationally with the Keller-Box implicit finite-difference technique. Extensive for velocity, surface temperature, skin friction and heat transfer rate are visualized for various thermophysical parameters. Validation is conducted with earlier work for the case of a vertical plate in the absence of magnetic field, radiative flux non-Newtonian effects. The dimensionless entropy generation is obtained via the reduced and energy equations. Bejan number is generally decreased with greater values of number. Increasing magnetic field reduces entropy generation number whereas it the Bejan number. Increasing Brinkman number (dissipation parameter) is found to the entropy generation number whereas it suppresses the Bejan number.
