Effects of Hall and ion–slip currents on magneto–micropolar fluid and heat transfer over a non–isothermal stretching sheet with suction and blowing

In this work, the effects of Hall and ion–slip currents on the steady magneto–micropolar of a viscous incompressible and electrically conducting fluid is analysed using the theory of micropolar fluids formulated by Eringen. Heat transfer from a stretching sheet to a micropolar fluid is also considered. The derived fundamental equations on the assumption of small magnetic Reynolds number are solved numerically by employing the shooting method. Expressions for the velocities and temperature fields are obtained, and the effects of the various parameters of the problem, e.g. the magnetic parameter, Hall parameter, ion–slip parameter, mass transfer parameter and power–law exponent parameter, are discussed through graphs.
