abstract

We report measurements of the torque required to restrain a polycarbonate spindle surrounded by ferrofluid in a cylindrical container and subjected to the rotating field generated by a two-pole magnetic induction motor stator, as a function of applied field amplitude and frequency, and for various values of the geometric aspect ratios of the problem. Simultaneously, an ultrasonic method was used to measure the azimuthal velocity profiles in the ferrofluid contained in the annular gap of our apparatus. These measurements are compared to a rigorous regular perturbation solution in the small parameter Ωτ (Ω = frequency and τ = ferrofluid magnetic relaxation time) of the ferrohydrodynamic flow problem in the zero spin viscosity and linear magnetization limits.
