viscosity (μ) and thermal conductivity (κ)], Hall current (m), magnetic field (M) and
suction/injection (Ws) on steady MHD laminar flow of an electrically conducting fluid on a
porous rotating disk in presence of a uniform magnetic field. The fluid properties are taken to
be strong functions of temperature. The induced magnetic field is neglected while the
electron–atom collision frequency is assumed to be relatively high, so that the Hall effect is …
