Theoretical analysis of oscillatory flow of a magnetic fluid in a circular pipe in a nonuniform magnetic field is conducted by taking into account the aggregate of magnetic particles. As a model of the particle aggregate, and elongated ellipsoid is considered. In the numerical calculations, the effects of the frequency and applied field on the velocity distribution of oscillatory flow are classified. Also, the effect of the applied field on the amplitude of fluctuating pressure is compared with the experimental data obtained by the authors. A reasonable agreement is obtained between theory and experiment if the elongated ellipsoid particle aggregate is assumed.
