Steady Electrical Mhd Mixed Convection Flow of Nanofluid Under the Influence of Exponentially Decreasing Freestream Velocity with the Effect of Heat Generation/Absorption

Abstract

The present analysis is about the simultaneous effect of magnetic energy, electrical conductivity and heat generation/ absorption of a steady laminar incompressible nanofluid under the influence of exponentially decreasing free stream velocity. Using the non-similarity transformation the coupled nonlinear partial differential equations governing the flow are made dimensionless. Non-linear differential equations are solved by implicit finite difference scheme in combination with quasilinearization technique. The effect of factors such as Brownian motion parameter, thermophoresis parameter, Lewis number, buoyancy parameter, magnetic parameter, heat generation or absorption parameter are investigated on the dimensionless velocity, temperature and nanoparticle concentration profiles and their respective gradients. It is found that, the presence of electrical field, magnetic field and nano particle concentration have prominent effects on fluid flow and heat transfer characteristics. © 2019 by American Scientific Publishers.
