Effect of Hall parameters on MHD flow of Nano fluids Due to Non- Coaxial Rotation of a Porous disk and a Fluid at infinity

Abstract

The unsteady viscous incompressible nanofluid flow is investigated analytically for copper water nanofluids under the effects of heat transfer and a uniform transverse magnetics field with the thermo physical properties, in which the flow is established between the non-coaxial rotations of a porous disk and a fluid at infinity. In this investigation, we consider that the studied nanofluid is electrically conducting and Hall currents are taken into account. . In a special case, the present numerical solution is validated analytically and numerically with the earlier available results. The effects of major parameters on the dimensionless velocity, temperature and volumetric fraction of nanoparticles are analysed via representative profiles, whereas the skin friction factor and the heat transfer rate are estimated numerically and discussed through tabular illustrations.
