Hall impact on the MHD fluid flow and heat transfer with uniform radial electric field due to a stretching rotating disk

Abstract

In the current paper, the steady flow of an incompressible electrically conducting fluid and heat transfer are studied. In these, we consider the Hall effect over an infinite stretching rotating disk in presence of a magnetic field. Navier-Stokes equations, Maxwell equation and energy equation have been modified in the presence of the Hall impact. Moreover, the uniform magnetic field, and the radial electric field are applied. With the help of the usual similarity transformations, these modified equations are simplified to a set of nonlinear ordinary differantial equations. Numerical solutions of the equations are obtained by using the Chebyshev collocation technique for different values of the entire of the physical parameters. The accuracy of the method is verified by comparing with the results in the literature. The influences of Hall parameter in these equations system are depicted graphically and analyzed.
