Abstract: Numerical analysis of a steady magnetic fluid flow in a straight pipe is made by taking into account nonuniform distribution of mass concentration and formation of prorate spheroids of magnetic particles under a steady nonuniform magnetic field. The local shear rate, number of aggregated particles as a prorate spheroid and fluid velocity distribution are obtained to be clarify that their large change exists at the down stream area of the magnetic field. The relation of wall friction to Reynolds number shows good agreement with the experimental data.
