Abstract :In this paper the steady Von Kármán flow of incompressible fluid in which the Hall effect exists is analyzed over the infinite rotating disk with additional assumptions: the uniform magnetic field applied normally to the disk and the radial electric field imposed to the disk. Therefore, the stability equations and energy equation have been modified in the presence of Hall effect, uniform magnetic field and radial electric field. The system of equations generated by stability and energy equations has been solved using Chebyshev collocation technique for varying values of Hall parameters, magnetic interaction and radial electric parameters. Accuracy of the method is verified comparing results in the literature. Effects of parameters are depicted graphically and are analyzed.
