Heat transfer over a stretching porous surface on a steady MHD fluid flow

Abstract

In clinical and medical research the magnets are extremely important to create three-dimensional images of anatomical and diagnostic importance from nuclear magnetic resonance signals. The steady MHD convective flow of viscous nano-fluid is brought about by a permeable exponentially extending surface has been discussed in this chapter. Water is considered as base fluid, while nanoparticles comprise Cu and Al₂O₃. Fluid is electrically conducting subject to applied magnetic field with constant strength. Similarity transformations, to an ordinary differential condition, minimise the non-linear partial differential equations governed the flow with convective boundary conditions. Convergence of the solutions is obtained. A parametric study of the physical parameters for velocity and temperature is carried out and the local shear stress and Nusselt number near plate are shown graphically along with a set of statistical results.
